AbstractConcrete today is recycled, placed faster, transported to higher locations and used under cold and hot arid conditions because of the continued evolution of chemical admixtures. The new generation of admixtures affords designers and contractors more control over the properties they want in a concrete mix. Current concern over salt damage to concrete, the alkali-aggregate reaction, the need to produce more durable structures, make some admixtures more topical than others. For these reasons, chemical admixtures such as superplasticizers and supplementary cementing materials such as silica fume and fly ash is the subject of increased interest. The combined use of these materials produces synergistic effects, which result in a range of modifications enabling highly durable concretes to be placed under a variety of conditions.
