Influence of Silica Fume on Mechanical Property of High Performance Concrete

Article Preview

Abstract:

Silica fume is a by-product in the production of ferrosilicon and industrial silicon material. With the ultrafine physical structure of and high volcanic ash activity, silica fume is more important admixture in concrete improving the strength and durability of concrete, and it is widely used in high performance concrete engineering. Influence of silica fume on mechanical property of high performance concrete is investigated in this paper. Experimental results show that the strength of concrete increases significantly when suitable dosages of admixtures is applied.
