High Strength and High Performance Concrete

Manufacturing of high performance concrete, which is majorly used as building material in the major and huge infrastructure projects, is a daunting task. This research was considered to be essential to measure of both physical and mechanical properties and durability characteristics of high performance concretes containing blends of Portland cement and supplementary cementitious materials. The main object of this research is to evaluate the structural strength of high performance concrete by using supplementary cementitious material. Water-cement ratio of this experiment kept from 0.32 to 0.35. The test variables included the type and the amount of supplementary cementitious materials (SCMs) such as silica fume (SF), Fly ash (FA). Portland cement replaced up to 30% by supplementary cementitious materials. Fly ash was replaced in both 1.1 and 1.2 ratios. Concrete was tested after 7 days and 28 days. For mechanical properties of concrete various tests were performed like Compressive strength test, Split Tensile strength test, Flexural strength test. This study helps in identifying influence of silica fume (SF) & Fly ash (FA).
