Abstract

The invention discloses a plaster block and preparing method through chemical plaster and industrial waste material, which is characterized by the following: the chemical plaster is allocated by anhydrous gypsum with different hydrating speeds and hydrated crystal structures at 2: 1-3: 1 into semi-plaster through frying; the rate of cement in the hydrating course and anhydrous gypsum rate in the micro-bulking course is 1:12-1:3; the air-entrainer is added in the raw material, which generates dispersing micro-bubble without light-weight aggregate.

Description

technical field

[0001] The invention relates to a gypsum block for a non-load-bearing internal partition wall of a building and a preparation method thereof, in particular to a gypsum block with strong water resistance and good sound insulation made of chemical gypsum and industrial waste and a preparation method thereof. Background technique

[0002] Most traditional gypsum blocks use natural dihydrate gypsum (or chemical dihydrate gypsum) to make hemihydrate gypsum, add a certain amount of lightweight aggregate (some also add a small amount of fly ash and other admixtures), add water and stir, Formed by pouring. Although its production process is simple, the product's flexural and compressive strength can meet the requirements of the specification, and it also has certain thermal insulation and thermal insulation building performance, but due to the high cost, especially the poor water resistance, it is widely used in toilets, kitchens and other parts. Additional waterpro...
