Abstract

The invention discloses a bottom plastering gypsum powder, which belongs to a building material and solves the problems of high energy consumption in cement production and reduction of the use area due to high consumption when the gypsum powder is used as a building construction material. The invention relates to a bottom plastering gypsum powder which is prepared from the following raw materials in parts by weight: 20-60 parts of semi-hydrated gypsum powder, 10-40 parts of anhydrous gypsum powder, 1-10 parts of fly ash, 1-20 parts of quartz sand, 0.1-2 parts of polyvinyl alcohol (PVA), 0.5-2 parts of carboxymethyl cellulose (CMC), 0.1-0.5 part of methyl cellulose (MC) and 0.1-2 parts of citric acid. The components are pulverized, ground and mixed for 10-60 minutes or subjected to secondary stirring to obtain the bottom plastering gypsum powder. The bottom plastering gypsum powder has the advantages of low energy consumption, simple preparation method, safe and harmless product and wide application range.

Description

technical field [0001] The invention belongs to building materials, and in particular relates to a material suitable for painting on brick walls after building construction, in particular to a bottom plaster plaster powder. Background technique [0002] At present, cement mortar is generally used as wall material in the construction industry. During construction, a thick layer of cement mortar is applied on the brick wall to ensure the smoothness of the wall surface. According to statistics, my country's cement output in 2013 was 2.42 billion tons per year, equivalent to more than the sum of other countries. After the ban on solid clay bricks, cement increased from 2003 to 2013. [0003] 1.7 billion tons. However, cement is a high-temperature calcined material that needs to be calcined at a temperature of more than 1400 degrees, so the energy consumption of cement production is very large. [0004] The calcination temperature of gypsum is about 200 degrees. Compared with t...
