Abstract

This paper presents the result of mix design developed for high strength concrete with silica fume and High range water reducing admixture (HRWR). It involves the process of determining experimentally the most suitable concrete mixes in order to achieve the targeted mean strength. In this research work 53 grade ordinary Portland cement, the locally available river sand, 10 mm graded coarse aggregate were selected based on ASTM C 127 standard for determining the relative quantities and proportions for the grade of concrete M60. For this design ACI 211.4R-93 guidelines were followed. Totally Five mixes were designed one mix was treated as basic mix with HRWR-0.5% without silica fume, Four mixes were designed with Micro silica quantities varied from 5 to 9 percent weight of cementitious materials and HRWR varies between 0.6% to 0.9% with increment of 0.1%. Each mix 2 numbers of 150mm x 300 mm cylinders were cast then kept in curing tank after 24 hours of time period. After 28 days of curing the specimens were tested and the appropriate mix proportions were obtained.
