Abstract
Disclosed is a rock similar material satisfying a water-induced strength degradation characteristic and a preparation method and use thereof. The rock similar material satisfying the water-induced strength degradation characteristic includes an aggregate, a cementing material, and an additive, where the aggregate includes quartz sand, barite powder, and bentonite, and the cementing material includes cement and gypsum.
Claims9
A rock similar material satisfying a water-induced strength degradation characteristic, comprising an aggregate, a cementing material, and an additive, wherein the aggregate comprises quartz sand, barite powder, and bentonite, and the cementing material comprises cement and gypsum;
- wherein the bentonite accounts for 15-20% of a total mass of the aggregate and the cementing material;
- the additive comprises a gypsum retarder;
- wherein a mass ratio of the aggregate to the cementing material is 4:1;
- and
- wherein a mass ratio of the cement to the gypsum in the cementing material is in a range of 3:7 to 7:3.
