PREFACE

Extensive study by the Division of the expansive reactivity shown by dolomitic limestone from Kingston when used as the coarse aggregate in concrete has led to a reasonably complete

picture of the performance of the aggregate. Work is proceeding in an attempt to discover the

specific reactions involved. Studies are being made of the chemical and mineralogical compositions of rock from beds at various depths in one of the quarries, in the hope that some correspondence between composition and reactivity ｭｾｹ be found which will indicate more clearly the role which composition may play in the reaction. The chemical analyses which have been carried out are now

reported and examined. The author, a research officer with the Building Materials Section, has had special experience in the application of various techniques for mineralogical analysis.

CHEMISTRY OF THE KINGSTON DOLOMITIC LIMESTONE

by

J. E. Gillott

The expansive reactivity with cement alkali

dis-played by the argillaceous dolomitic limestone from Kingston, Ontario, has been previously described (11, 12, 13). A

comparative chemical investigation intended to throw light on the mechanism or causes of the reactivity is described in this report. This study was carried out in conjunction with a petrographic and mineralogical investigation described in another report (5).

Sampling was restricted to particular beds in one of the operating quarries near Kingston. Rock was obtained at depths of 6 to 7 ft, 10.5 to 12 ft, 20 to 21 ft, and 24 to 30 ft from the surface and it was hoped that within these beds there would be constancy of chemical composition so that a direct comparison could be made both between the selected horizons and between the rock and aggregate. The rock was

crushed and sized and used as aggregate in beams made with high and low alkali cement and similar beams were made in Which non-reactive Ottawa Valley limestone was used for

aggregate. After several months under conditions of 100 per cent relative humidity and constant temperature, linear

measurements on the concrete beams indicated that the

expansive reaction had occurred in the aggregate. The beams made with high alkali cement varied in the rate at which

they expanded (5). The maximum rate was shown by the beam made with aggregate from the 20- to 21-ft bed. Aggregate from the 10.5- to 12-ft bed produced expansion at a rate similar to that produced by composite aggregate from the top 24 ft in the quarry; aggregate from the 6- to 7-ft bed was less reactive and that from the 24- to 30-ft bed showed only

slight reactivity. The Ottawa Valley rock produced no expansion.

TREATMENT OF SAMPLES

The beams were brolcen up and the aggregate separated from the adhering cement paste by hammer and chisel. The final clean-up was accomplished with a dentist's drill, each piece of aggregate being treated separately while held in a vice. This process was lengthy and only a few grams of aggre-gate were obtained from which it was certain that cement

paste had been completely removed. The sampling was therefore probably less representative than in the case of the untreated rock. From this point the rock and aggregate were treated similarly.

2

-The material was ground to pass a 100-mesh sieve and

a split of 5 gm set aside for chemical analysis. A similar,

though larger, split was stirred overnight in cold 4 molar

acetic acid to separate about 5 gm of the acid insoluble

fraction. This was washed free of acid by repeatedly

centrifuging with distilled water.

A concentrate of dolomite from the 6- to 7-ft, 10.5-to 12-ft and 24- 10.5-to 30-ft rock was also obtained, by a

separation procedure which involved five stages. These

stages were:

(a) The sample was carefully ground by hand and put

through a series of sieves placed one above the other. This

procedure ensured that a reasonable proportion was retained on 325 mesh while a greater proportion of clay material passed through as fines.

(b) The fraction retained on the 325-mesh sieve was

treated with 4 molar ammonium acetate to dissolve calcite adhering to the dolomite which is relatively less soluble.

(c) The sample was filtered and washed and repeatedly

put through a sedimentation column using calgon to disperse the remaining clay minerals.

(d) The sample was dried and centrifuged in heavy

liquids of specific gravity 2.68 and 2.80, to remove quartz and calcite as light fractions, and in liquid of specific gravity 3.0 to remove the heavy minerals from the lighter dolomite.

(e) A Frantz isodynamic magnetic separator was finally

employed to give fairly pure dolomite. Graphitic and

bituminous material, apparently intergrown with clay minerals was removed at this stage.

In the case of the aggregate there was insufficient starting material to allow enough dolomite to be concentrated for

chemical ,analysis though in every case sufficient was obtained for examination by x-ray diffraction.

The chemical analyses were performed by means of

the "rapid methods" under the supervision of

Dr.

J. A. Maxwell

of the Geological Survey of Canada at the request of the

Division of Building Research. The results are set out in

Table B-1 of Appendix B.

-minerals might make easier the comparison of analyses if mineral ｾｬ｡ｳ･ｳ with the same chemical compositions could be

computed in each case. Imbrie and Poldervaart (8) recently described a scheme upon which the mineral recalculation adopted here was based.

Details of the calculation are set out for the Ottawa Valley rock in Appendix A and results for all the samples, similarly computed, are shown in Appendix B. Section (i) of the Imbrie-Poldervaart scheme was followed as described by the authors except that L.O.l and H

20- were not available and calculations based upon these values were omitted. It was also assumed that only 20 per cent of the sulphur was

combined as pyrite as it was found that for some of the samples uncombined sulphur would remain even if all the divalent cations were used. The figure of 20 per cent is arbitrary but ensures that at least some ferrous iron remains after the calculation of pyrite in each case. The excess of sulphur indicates that this element is present in

some other compound than pyrite, which is known to be present, and one may speculate that it is combined in some form of organic compound as carbon content is quite high and sulphur

is a biophile element

(7).

The group S03 was not included in the determination and gypsum was not calculated.

For the calculation of the clay fraction the divalent ions magnesium, iron, and calcium were combined and the

molecular weight of the clay minerals adjusted accordingly depending on the amount present. The same procedure was followed for Al

203 and Fe20 3 which for chlorite and montmoril-lonite were combined and the molecular weight computed on the bases of a weighted average for R

203• The molecular weight of illite was computed on the assumption that only A1

203 was present as for certain of the rocks there was insufficient Fe

20 3 for even 1 mole per illite mole.

All the analyses of the acid insoluble fraction except that of the Ottawa Valley aggregate fell within field (ii) C of the Imbrie-Poldervaart scheme but in many, the supply of R

20 3 became exhausted prematurely. It was found, however, that this difficulty could be overcome if

picro-phengite was calculated instead of sericite. When the "total rock" analys es were considered it was found that if the

chemical formulae assumed in this scheme were followed the samples fell within different clay mineral fields. Since comparison between the samples was the main purpose for the calculation the assumptions made as to chemical compositions were adjusted so that the same minerals could be computed in

20 and less H20 and less MgO.

There is less replacement of silica by trivalent ions and more vacancies have had to be assumed in the tetrahedral layer. The formula adopted does not necessarily bear more than the most general relationship to the true composition of the mineral present in the rocks. In the illite which actually

occurs in the Ottawa Valley limestone, for example, the degree of hydration is certainly greater than in the Kingston samples but the same composition is assumed for both in the calculation.

The chlorite formula was also modified so that more

divalent and less trivalent ions would be ｵｾ･､Ｎ The structural formula in this case can be represented as

The amount of illite, chlorite, and montmorillonite computed depends respectively on the amount of K

20, R"O and R

203 and these oxides are disposed of successively in this order. _{The moles of illite are given by (K20)/(3.5), of}

chlorite by PI/5, and of montmorillonite by ｕＯＲｾ p' being the moles of R"O remaining after illite and U the moles of R₂₀

₃

remaining after illite and chlorite. The ratio (l.9H)/(3.5F·), had to be less than unity in every case if there was to be

R"O available for the formation of chlorite after illite and the values 1.9 and 3.5 were arbitrarily arrived at to ensure that some R"O would remain unused after illite. Similarly the amount of R

203 used in each mineral was derived in such a manner as to ensure an excess after the computation of illite and chlorite and the balance was computed as mont-morillonite. Unused Si0

2 was computed as "chert". In the

case of both silica and water a deficit occurred for certain of the analyses and while it does not affect the value of the

computation for comparative 'purposes it emphasizes that the compositions assumed for the minerals are hypothetical.

5 -DISCUSSION OF RESULTS

Various graphical plots were made of the oxide percentages and computed mineral percentages but in no case was a

clear-cut relationship found between reactivity and composition. Figures 1 and 2 show percentage oxide plotted against percent linear expansion in conorete beams which had been leept for

ｾｬ･ same time under high humidity conditions. There seems to be no maximum in the percentage curve of any oxide which corresponds with the most expansive concrete.

When plotted in order of increase in depth from surface of the quarry the Kingston rock shows an increase in 8i0

2, A1

203, K20 and FeO (Fig. 3). The Ottawa Valley material is in many ways similar in composition to the Kingston 10.5- to 12-ft bed but differs from the Kingston samples in that it has a lower content of ｾｾｏ and a higher carbon and sulphur

content. The plot of the acid insoluble fraction (Fig. 4) shows that all of the beds have a similar content of CaO and FeO.

MgO is similar in the Kingston beds but as with the analysis of the "total r-ock" there is less in the Ottawa Valley

sample. The form shown by the silica curve is similar to that which it shows in the total rock analysis, but differs

from that of the Al

20 3 curve which suggests that free silica has a maximum in the 24- to 30-ft bed where Al

203 has a minimum. Carbon and sulphur both increase from the 24- to 30-ft bed

towards the Ottawa Valley sample.

The form of the curves displayed by the aggregate is not exactly the same as for the untreated rock (compare Figs. 3 and 5 with 4 and 6) but values close to unity are obtained

when the oxide ratios are computed so that it seems likely that little chemical change has occurred. Rims, similar in appearance to those surrounding Kingston aggregate, have been described by Bisque and Lemish (1) who have shown

silicification to be the cause, the silica being derived from the cement paste. In the three reactive Kingston beds there is .more silica in the analyses of the aggregate than of the rock but less silica is indicated for the Ottawa Valley and 24- to 30-ft samples. The acid insoluble fraction however shows that this does not necessarily represent a relative

increase or decrease in the proportion of silica to the other insolubles. In the Ottawa Valley (acid insoluble) the silica increase is matched by an increase in alumina and this trend continues in the 6- to 7-ft and 10.5- to 12-ft beds though the alumina increase is relatively greater than the silica increase. In the 20- to 21-ft and 24- to 30-ft beds there is a fall in the proportion of silica but an increase in the amount of alumina (Fig. 7). One ｾｯｵｬ､ thus expect less free

-silica in the aggregate than in the rock in the 20- to 21-ft and 24- to 30-ft beds. It seems likely that the chemical changes which may have occurred are small and the major differences between rock and aggregate probably result

from variation between different parts of the same bed. This variation was not entirely eliminated due to sampling diffi-culties in the case of the aggregate. This view is reinforced by the correspondence, in both the aggregate and rock, between the form of the curve of acid insoluble and 8i0_2, A1

20 3, and K₂₀ (Figs.

3A,

5A).

The H₂₀ curve crosses the K

20 curve at the 10.5- to

12-ft bed in both the rock and aggregate analyses (Figs. 4, 6). The plot of the K20/H20 ratio (Fig. 8) for acid insoluble of both rock and aggregate shows that the three reactive beds are similar with respect to this ratio while the 24- to 30-ft

bed is high and the Ottawa Valley sample low. This is most probably a reflection of increased hydration in the mineral illite in the Ottawa Valley samples which was also deduced from the form of the 10 ! peak on diffractograms (6).

As suggested previously a consideration of the curves for 5i0₂ and Al

203 suggest a maximum for free 8102 in the 24- to 30-ft bed. This is made more apparent when the 8i0

2/Al 20 3 oxide ratio is plotted (Fig.

9).

On this interpretation more uncombined silica should also be present in the Ottawa Valley samples than in the three reactive Kingston beds.

The computation of carbonate (Figs. 10, 12) indicates high calcite in the Ottawa Valley rock and a minimum in the

24- to 30-ft rock. The content of dolomite is a minimum for the Ottawa Valley sample. The carbonate composition is

shown by the calcite-dolomite ratio which is a maximum for

the Ottawa Valley limestone and a minimum for the 24- to 30-ft bed. The illite curve for the total rock and total aggregate

is similar in form to the oxide plot of Al

203, 8i02 and K20

(Figs. 10, 12). In the computations based on the analyses of the acid insolubles the formation of illite from K20, Al203 and 8i0

2 is also reflected by the similarity between the form of the mineral and oxide curves (Figs. 11, 13). The albite curve has a shape similar to that displayed by Na_20. The importance of divalent cations in the assumed formula for

chlorite may also be seen by comparing Figs. 11, 13 and 14. The latter figure also shows an interesting similarity between

the curves of R

As the computation has been made on a common basis for all samples one should theoretically obtain similar

trends for the clay minerals computed in the "total" analyses as in the acid insoluble fractions. This in general is not found and presumably limitations of the analytical techniques prevent such a rigid comparison when a recombination into clay minerals is attempted. For these minerals greater

significance is attached to the values obtained in the analyses of the acid insoluble fractions, where quantities to be

determined are larger. It is of interest that on the

assumptions made in this computation the value for "chert", which represents uncombined Si0

2, has a maximum for the 24-to 30-ft bed and there is apparently more uncombined Si0

2 in the non-reactive Ottawa Valley limestone than in the highly expansive 6- to 7-ft and 10.5- to 12-ft beds.

The chemical analyses of the dolomite concentrate show no manganese and only just over 1 per cent ferrous and

ferric iron.

CONCLUSION

The computation adopted shows that if the same

minerals are to be calculated for each sample rather drastic modifications have to be made to the formulae for the clay-minerals proposed by Imbrie and Poldervaart, even though

other techniques have shown the rocks to be similar mineral-ogically. On any assumption it seems clear that for certain of the rocks the sulphur content is too high for pyrite to be the only sulphur-containing material in the rock and it appears most likely that the sulphur is combined with carbon.

The K20/H20 ratio is a chemical reflection of mineralogical differences in the illite.

All the rocks considered in this report contain

less than 50 per cent acid insoluble and they are, therefore, properly classified as carbonate rocks (e.g. Carozzi (2)

p. 193).· There are in the literature detailed discussions of the chemistry of limestones and dolomites and there are various suggested classifications of these rocks based upon chemical composition (Pettijohn (9), p. 417; Cayeux, (3)). According to one such scheme and the mineral computations followed in this report the rock and aggregate fall into the folloWing fields: Ottawa Valley 6 to 7 ft Rock limestone calcitic dolomite Aggregate magnesian limestone dolomitic limestone

10.5 to 12 ft 20 to 21 ft 24 to 30 ft 8 -Rock calcitic dolomite dolomitic limestone calcitic dolomite Aggregate dolomitic limestone dolomitic limestone dolomite

The three most reactive rocks are intermediate in composition between limestone and dolomite and according to several authorities such rocks are relatively less common

than the end members of the series (Steidtman (10), Pettijohn (9), p. 417). On the other hand, the analyses of the acid insoluble fraction of the limestones are quite similar to one given by F. W. Clarke (4) for an "average shale".

The graphs show no apparent relationship between oxide, or computed mineral composition and reactivity apart from the suggested significance of the dolomite calcite ratio. If this is indeed significant it seems most likely that

there are additional, still unknown factors which lead to the great expansivity shown by the 20- to 21-ft bed.
