Abstract
This article starts with the characteristics of cave slag tailings, proposes to optimize the quality of the concrete production process and product structure by improving the composition of concrete fine aggregates, and conducts research on the key technologies of the application of cave slag tailings to concrete. Concrete quality and economic cost are the basic frameworks, and the feasibility of using cave slag tailings is comprehensively analyzed. It has been verified by experiments that the application of cave slag tailings can greatly improve the stability of concrete production process, reduce concrete structural defects and quality disputes caused by process control, and can significantly reduce the cost of single main material of concrete and bring good Economic benefits. At present, the slag tailings of the cave have been widely used in the resettlement houses of Houyu, Minhou, the MIXC# building, TA# building and its basement of the fourth phase of Fuzhou China Resources Vientiane City, and all performances have reached the engineering design requirements.
