Abstract:

To design a reasonable packing material, solve the problem of solid pollution brought by the iron ore mining, alleviate a lot of backfilling affect national economic development and the current situation of environmental governance. Backfilling materials in this paper, we study the different water-cement ratio pack slump and uniaxial compressive strength and discusses the workability of water-cement ratio on filling body and the influence of uniaxial compressive strength. The experimental results show that with the increase of water cement ratio, the filling body's workability is better and uniaxial compressive strength is lower. When water cement ratio is 0.4, workability and strength of filling body is the best. The experiment provide reliable data for engineering application practice, at the same time to provide reference for other related experiment.
