Abstract: Silica fume is a by-product of electric arc furnace reduction of quartz into silicon and ferrosilicon  alloy used in the electronics industry. This is composed mainly by silicon and this by-product can be used as a mineral admixture in mortar and concrete. This waste product is already causing serious environmental pollution which calls for urgent way of handling the waste. In this paper, silica fume has been chemically and physically characterized, in order to evaluate the possibility of their use in industry. Samples of varied amount of silica fume mix with cement at 0, 5, 10, 15, 20, 25&30 % respectively. Aging times were 28 days for compression strength.

Keywords: Interlocking concrete block pavement (ICBP), Silicon, SUDs
