Abstract

The invention discloses a wall plastering and building solidifying material and belongs to a building material, in particular to a material for use in wall plastering. The wall plastering and building solidifying material is prepared by mixing the following main materials: 15 to 50 percent of cement, 20 to 65 percent of active admixture, 2 to 18 percent of lime powder, 0.05 to 0.2 percent of surfactant, 0.5 to 2 percent of water-retaining thickener and 0.5 to 1.5 percent of dispersible polymer. The solidifying material of the invention can replace cement or other gelling materials to be mixed with sand and water in proportion to prepare wall plastering and building mortar for aerated concrete block walls and common walls. When the solidifying material is used, the interface processing of the walls is saved. The solidifying material has the characteristics of high binding strength, low shrinkage and high strength. When the solidifying material is applied in wall projects, time-saving, labor-saving and environmentally-friendly effects can be achieved.

Description

technical field [0001] The invention belongs to building material technology, in particular to a wall plastering and masonry solidification material. Background technique [0002] Among the current wall plastering masonry materials, the traditional material is cement mortar, which is directly prepared from cement, sand, and water. The disadvantages of this material are that the amount of cement is too large, the cost is high, and it is not suitable for the development of new wall materials. . Now air-entrained concrete has been used in more than 70% of civil buildings in my country's cities. Due to the rough surface and strong water absorption of air-entrained concrete, traditional cement mortar needs to be pre-soaked when used on air-entrained concrete walls. surface treatment. On the basis of this treatment, the traditional mortar used for plastering and masonry is still prone to problems of shrinkage cracking, chalking and low strength. Therefore develop a kind of setti...
