Siliceous cementation structural surface interlayer similar material and preparation method thereof
The invention relates to a siliceous cementation structure surface interlayer similar material and a preparation method thereof, and belongs to the technical field of similar materials, the siliceous cementation structure surface interlayer similar material comprises aggregate: quartz, feldspar, mica, chlorite and calcium carbonate powder; curing agents: gypsum and sodium silicate; the blender comprises water, borax, a water reducing agent and graphene oxide. The mass ratio of the quartz to the feldspar is 2-0.5; the sum of the mass of the mica and the chlorite accounts for 0-15% of the total mass of the aggregate; the calcium carbonate powder accounts for 0-5% of the total mass of the aggregate; the gradation and the content of each aggregate are determined by the mineral gradation and the content of the interlayer of the original rock structural surface; the dosage of the blender is fixed to be 30% of the mass of the curing agent, and the ratio of the graphene oxide to the curing agent is 0-0.06%. The mass ratio of the aggregate to the curing agent is 0.5-2; and the mass ratio of gypsum to sodium silicate in the curing agent is 0.5-2. According to the invention, the development of materials with similar tensile strength, shear strength and disturbance damage characteristics of the original rock structural surface is realized, and the problem of material source research of the hard structural surface of deep engineering is solved.
