摘要

The effects of silica sol addition on the physical properties of silica based castables were researched by using used silica brick particle of 5-3mm, 3-1mm and 1-0mm as aggregates, used silica brick fine power of 0.088-0mm, micro-silica powder and silica sol as matrix.The ratio of aggregate to matrix is 65:35.The results show that the flowability of matrix of silica based castables increases with the addition of silica sol, but when the addition of silica sol is more than 4％,the flowability decreases;When addition of silica sol is about 8％, the specimens possess larger B.D.,smaller A.P.and PLC;CMOR, CCS and HMOR of specimens heated at 11 00 ℃ are better when addition of silica sol is about 6-8％;When the addition of silica sol is about 8-10％, CMOR, CCS and HMOR of the specimens heated at 1450 ℃ are better.
