Abstract

The invention provides a special caulking agent for ALC installation, and relates to the technical field of building materials. The special caulking agent for ALC installation comprises Portland cement, quartz sand, redispersible latex powder, hydroxypropyl methyl cellulose ether, calcium formate, starch ether, polypropylene fiber and limestone powder. The caulking agent comprises the components in percentage by weight: 25 to 35 percent of Portland cement, 55 to 65 percent of quartz sand, 2 to 4 percent of redispersible latex powder, 0.1 to 0.5 percent of hydroxypropyl methyl cellulose ether, 0.05 to 0.2 percent of calcium formate, 0.05 to 0.2 percent of starch ether, 0.1 to 0.5 percent of polypropylene fiber and 5 to 10 percent of limestone powder. The special caulking agent for ALC installation provided by the invention is small in dry shrinkage deformation, has good crack resistance, workability and water-retaining property, has relatively high binding power with a wall material or other base materials after being hardened, so that a connecting interface is not easy to crack, the connecting stability is better, cracking of inner and outer walls can be completely prevented, and meanwhile, the bonding speed is relatively high; and the preparation process is simple, convenient and fast, and the construction efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a special caulking agent for ALC installation. Background technique [0002] ALC is the abbreviation of autoclaved lightweight concrete, which is a kind of high-performance autoclaved aerated concrete. The ALC board is made of cement, quartz sand (or fly ash), lime, etc., and is cured by high-pressure steam. Porous concrete forming board (containing treated steel reinforcement), ALC board can be used as wall material and roofing board. It is a new type of building material with superior performance. This building material not only has good thermal insulation performance, but also has Excellent thermal insulation performance, when using a reasonable thickness, it can not only be used in cold areas with high thermal insulation requirements, but also in hot summer and cold winter areas or hot summer and warm winter areas with high thermal insulation requirements, meeting ...
