Mechanism of sand what are the implications for CGM high-strength non-shrinkage grouting material - Bearing grouting material

We may understand the mechanism of sand shortening can restrict high-strength non-shrink grout material, shortening the CGM high-strength non-shrinkage grouting material several times than cement, sand mechanism of the influence of the characteristic of concrete grouting material function first embodied in the following aspects: 1, the mechanism of sand particles in high-strength non-shrink grout guess can rise the skeleton effect, constraints between the deformation of the cement and aggregate sliding; 2, the mechanism of sand surface is rough, and then increases with high-strength non-shrinkage grouting epoxy resin grouting material interface bond strength; Remains a rich in 3, the mechanism of sand stone powder, the powder improved hydration products of CGM grout material grouting material of crystal, crystal glue than progress to make high strength without shortening deformation of grouting material under the effect of external force decreased; Mechanism of 4, compared to natural sand, sand particle surface is rough, with pure mechanism sand mixing high strength without shortening of grouting material and poor workability. Above is the mechanism of sand with the introduction of the high-strength non-shrink grout material impact, expect some help to you.
