Abstract

The invention is suitable for the technical field of building materials, and provides building solid waste recycled aggregate dry-mixed plastering mortar, which comprises the following components by weight: 25-35 parts of medium sand, 15-27 parts of cement, 20-40 parts of building solid waste manufactured sand, 8-13 parts of PP fiber, 0.5-1.5 parts of triethanolamine, 3-6 parts of ethylene glycol,3-6 parts of lignin calcium sulfate, and 4-8 parts of latex powder. The building solid waste manufactured sand is specifically treated by preferably selecting functional additives, so that the building solid waste manufactured sand can replace natural river sand, natural river sand resources are saved, and the cost is reduced; and meanwhile, the dry-mixed plastering mortar not only has good crackresistance, impermeability and abrasion resistance, but also has the advantages of high strength, micro-expansion, good fluidity, no corrosion, impact resistance, vibration resistance and the like, adapts to concrete walls with high requirements on crack resistance and strength, improves the product construction workability and operability, and meets the quality requirements of the building industry.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a dry-mixed plastering mortar of building solid waste regenerated aggregate and a preparation method thereof. Background technique [0002] Dry-mixed plastering mortar can be used for the plastering and plastering of various types of masonry and ceilings on the interior and exterior walls of buildings. It is suitable for wet construction techniques that require wet blocks before construction, general non-structural repairs, slope stabilization and platform smooth. [0003] However, with the continuous improvement of engineering quality, environmental protection requirements and civilized construction requirements, the shortcomings and limitations of mortar use have become more and more prominent. At present, there are various types of dry-mixed plastering mortars on the market, but most of them use natural river sand, and natural river sand resources are i...
