Abstract

The invention relates to an anti-seepage anti-corrosion cement-clay solidifying slurry, which is prepared from the following raw materials in parts by weight: 25 to 30 parts of common clay (water-free soil), 6 to 8 parts of kaolin, 3 to 6 parts of cement, 1 to 3.5 parts of curing agent, 0.5 to 1.5 parts of early strength agent, 0.01 to 0.1 part of organic stabilizer, and 55 to 60 parts of water. According to the anti-seepage anti-corrosion cement-clay solidifying slurry provided by the invention, the curing agent, the early strength agent and the stabilizer are added in a clay-cement slurry, so that the clay slurry with poor cementation becomes the anti-seepage anti-corrosion cement-clay solidifying slurry with short setting time, high erosion resistance, good mobility, simplicity in construction, and low cost, and the problem that the cement slurry is poor in solidification boundary fusion in an earth and rockfill dam, and the problems of ground stabilization, water sealing and leaking stoppage, anti-sloughing anti-settling project quality and reliability existed in geotechnical engineering are solved.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering materials in the subject of water conservancy and hydropower, in particular to an anti-seepage and anti-corrosion cement-clay solidified slurry and a preparation method thereof, which belongs to the technical field of grouting materials and is suitable for reservoirs, ponds, embankments, and mine tailings Anti-seepage or filling reinforcement treatment of dam and other projects. Background technique [0002] Most of the large and small ponds, reservoirs, and embankments in our country were built around the 1960s. In view of the material and financial resources and technical level at that time, most of the dams were earth dams. Due to historical reasons, the dam foundation of the water conservancy project was poor in quality, the quality of the filling materials for the dam body was poor, and there were hidden dangers of termites and mice gnawing. In addition, it was in disrepair f...
