Abstract

The invention discloses lightweight gypsum mortar. The light gypsum mortar is prepared from the following raw materials in parts by weight: 600-800 parts of desulfurized gypsum powder, 200-400 parts of heavy calcium carbonate, 50-100 parts of glass beads and 10-20 parts of an additive. The additive comprise the following components in parts by weight: 3-8 parts of hydroxypropyl methyl cellulose, 2-6 parts of a thixotropic agent, 3-5 parts of starch ether, 0.5-2 parts of redispersible latex powder and 10-20 parts of cement. The lightweight gypsum mortar has the advantages of greatly improving a production environment, batching precision, the labor intensity of workers and a labor utilization rate, fully utilizing the working time of the workers and improving production efficiency.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a lightweight gypsum mortar and a preparation method thereof. Background technique [0002] Gypsum is a gel material with a long history. It is listed as the three pillars of meta-mechanical cementitious materials together with lime and cement. The use of gypsum materials is of great significance for saving building material resources and improving the technical level of building materials. It usually has the characteristics of light weight, sound insulation, fire resistance, heat insulation, etc., and gypsum is rich in resources, so gypsum is widely used in the field of building materials. [0003] Mortar is a bonding substance used in building bricks. It is composed of a certain proportion of sand and cementing materials (cement, gypsum, clay, etc.) and water. It is also called mortar and mortar. Mortars generally include cement mortar, mixed mortar (cement-lime mo...
