Abstract

The enormous production of Ordinary Portland Cement is causing hazards to environment as well as reduction in natural sources though it is versatile materials and most important constituent of concrete.Due to this warning to ecosystem the researchers are directed to use industrial by products as supplementary cementitious material in usual manner in the present days in making concrete. In the experimentations, the silica fume is used as industrial by-product in normal concrete thereby increasing the mix design variables for which the mix proportioning is manysided. The prime intention of this paper is to investigate the various mechanical properties essentially on workability and strength. Compressive strength, Slump and Compacting factor tests of silica fume concrete are performed for strength and workability respectively. For this paper 15 (five) mixes of silica fume concrete are cast for experiments. Various cement replacement levels by silica fume for three water-cementitious material ratios of 0.40, 0.45 and 0.50 are used in experiments whereas other mix design parameters are kept unvarying. The cement replacement levels by silica fume are 0%, 5%, 10%, 15% and 20% for three water-cementitious materials (w/cm) ratio of 0.40, 0.45 and 0.50. Compressive strengths, compacting factors and slumps are evaluated at different age levels like at 24 hours, 7 and 28 days for both 100 and 150 mm cubes.
