The Effects of Mineral Admixture on the Compressive Strength of Concrete

Mineral admixture was one or more industrial waste, or mixed with finely ground natural minerals, or grinded mixture.By replacing part of the cement with mineral admixtures , cement could be saved and improved the performance of concrete. In this paper，the compressive strength and slump of the concrete with mineral admixture were tested. The amount of cement replaced by mineral admixture in the concrete affected the compressive strength and the slump. According to the compressive strength and slump of the concrete, the optimum dosage of the mineral admixture was from 30% to 40%.
