Abstract

The invention relates to seepage-resistant cement prepared from raw materials of, by weight: 5-8% of fluorine-containing polyacrylate emulsion powder with fluorine content of 1-3%, 2-3% of rosin with a specification of 100-200 meshes, 3-5% of sodium silicate, 3-5% of calcium hydroxide, 1-2% of alum, 1-2% of sodium dodecyl sulfate, 10-15% of phosphoaluminate cement, and balance of Portland cement. The cement provided by the invention is advantaged in high seepage resistance and high binding strength. With the cement, seepage resistance of cement mortar can be substantially improved, and bending strength and compressive strength of the cement mortar are improved.

Description

technical field [0001] The invention belongs to the technical field of polymer cement material research, and in particular relates to an anti-seepage cement. Background technique [0002] Through microscopic analysis, it can be known that cement will form four types of pores in the matrix during the hydration process: gel pores, transition pores, capillary pores and macropores. The total porosity of these pores, the distribution of pore diameters, the size and shape of the pores will all affect the compressive and flexural strength of the matrix. General cement-based composite materials are mainly composed of unhydrated cement clinker particles, hydrated crystalline minerals and gels of cement, water and a small amount of air. It is a solid-liquid-gas multiphase porous body. Therefore, buildings made of ordinary cement are bound to seep water. Therefore, it is necessary to lay a waterproof layer on the upper or lower layer of the cement product. In this way, the project c...
