mineral admixtures for high performance concrete

High

High-performance concrete (HPC) is produced by careful selection and proportioning of its constituents namely cement, sand, gravel, cementitious materials such as fly ash; silica fume; and slag, and chemical admixtures for instance high range water reducing admixtures. The strength and durability of the high-performance concrete exceed that of ordinary concrete. Therefore, the composition of Get price

Mineral Admixtures

In high performance concrete, this is the method of choice, since it increases the cementitious content. This increase is compensated by a decrease in the fine aggregate content. Addition method usually results in higher strengths.when fine materials such as silica fume are used, this method can cause a substantial increase in the water demand. Get price
