Production of High-Performance Silica Fume Concrete

Abstract

This research aimed to produce concrete that will decrease disadvantages of portland concrete and resolve it. Mixture of Silica fume with concrete in this paper shows that the strength and hardness are increased. In this research the main gools is to compare the deference of compressive strength between standred concrete and concrete with silica fume with different additives ratio and to explore its effect on the main physical properiets of concrete. To achieve our goals in this research about 180 samples prepared to examened it's compressive strength, all concrete sample has the same mixing ratio and distributing to standard and Silica fume added by the volume (5, 10, 15, 20 and 30%). The results show that the recommended addition was 15% of Silica fumes for optimum compressive strength that reaches 74.8 MPa. Also the economy of mixture compare to the market prices makes silica excellent to use as addition filler to concrete.
