lime to starl singing the praises of concrete's ail-round abilities
Our infrastructure and built-environment face growing pressure, flot only in terms of demands frOIDincreased use, but also frOIDthe need to meet the requirements oftoday's sus- tainability agenda to aileviate the predicted im- pacts of climate change which will add further pressure frOIDextreme weather patterns. These demands need to be met with an infrastructure and built environment that is bath efficiendy constructed and offers long-term performance with minimum maintenance.
Concrete,with its hast ofinherent benefits, provides the answer. Increasingly,its sustain- ability credentials ofbeing locaily sourced within the UK, of flot requiring additional finishes and preservatives, and its ability to provide holistic,long-term solutions, that address environmental, economic and social considerations are being recognised.
"The ideal of combining robustness with thin elegance is shown by the world's longest stress ribbon bridge"
The issues, projects and products covered in this issue of NewConcreteEngineering demonstrate the ability of concrete to provide solutions that are economic, efficient and environmentaily coherent. Concrete barriers, slab track and bridges ail offer unrivailed levels of robustness and minimum maintenance.
The concrete ideal of combining robustness with thin elegance is shawn by the world's longest stress ribbon bridge in San Diego, California. Concrete's ability to provide practi- cal answers that are unsung but essential is
highlighted by a range of surface water flood- ing and tunnel solutions. Its use for offshore wind farms and for proposaIs for generating electricity frOIDthe Severn Estuary tidal flow demonstrate its potential to provide renew- able energy solutions that will help to mitigate climate change.
Ali tao orteil concrete's contribution to our infrastructure and built-environment is taken for granted. It is an unsung hero. This issue of NewConcreteEngineeringsings its Fraises.
