Interior wall dry powder mortar

Abstract

The invention relates to interior wall dry powder mortar, which is prepared from the following raw materials in percentage by weight: 20 to 50 percent of desulphurization gypsum, 20 to 50 percent of artificial sand, 1 to 3 percent of water-retaining agents, 3 to 5 percent of wood fiber and 0.5 to 1 percent of composite retarders. The prepared interior wall dry powder mortar has the advantages that the raw materials use solid waste such as desulphurization gypsum and building decoration waste, so that the resources are saved; the environment pollution is avoided; the manufacturing cost is also reduced. The interior wall dry powder mortar has good workability and water preservation performance; the hardening of a floated coat is fast; the curing period is short; the advantages of strong bonding force, no shrinkage, no hollowing, no cracking, sound absorption, crack resistance and the like are also realized; the interior wall dry powder mortar is suitable for industrial production and popularization and application.
