DESIGN OF HIGH STRENGTH CONCRETE WITH ADDITION OF ADMIXTURES BY ACI 211.4R-93

Abstract

High Strength Concrete (HSC) is dense, homogeneous and has the improved engineering properties and durability as compare to conventional concrete. In recent years, HSC has gained wide application in the construction industry. Ingredients of HSC are similar as conventional concrete, such as cement, fine aggregate, coarse aggregate and water. The paste of HSC requires high volume of cement content and less water to binder ratio. The high strength and flowability of HSC can be achieved by employment of cement content, mineral admixtures and chemical admixtures. However, increasing the cement content causes high cost, higher heat of hydration and higher drying shrinkage. This can be reduced by employing mineral admixture such as fly ash. In the present investigation, cement content for HSC mix is replaced with fixed percentages of fly ash (10%).
