Abstract

This paper analyzed the mechanism of dilatation and high water retention of the independently researched new cementing material. It was proved by the experiment of dilatation and water retention behavior that the maximum water-solid ratio of this new material are 3:1 and the maximum volume dilatation rate of the backfill are 50.02%. The experiment of compression strength shows that the maximum uniaxial compression strength of the backfill can reach up to 9.73 MPa. The relationship of uniaxial compression strength with flexural strength and tensile strength were fitted by the least square method. Moreover, this paper explained the increasing law of the strength of the backfill in principal by analyzing its microstructure with Scanning Electron Microscope(SEM).
