Abstract:Currently, despite the large production, only about 10% of the fluorosilicates, a by-product from the phosphate fertilizer factories can be recycled, leading to no economic benefits. Moreover, the only way to dispose of fluorosilicates is discharging it into water, bringing about water pollution. However, fluorosilicate can be used as a basic material to improve the strength and hardness and then enhance durability of concrete according to a certain volume-to-weight fraction. In this paper, the enhanced performance of fluorosilicate on concrete was studied via the setting time of cement, the fluidity and strength of mortar, the mixing performance and the strength of the concrete. The enhanced mechanism was analyzed by XRD and SEM methods.
