Abstract

The invention discloses lightweight plastering mortar and a preparation method thereof. The lightweight plastering mortar is prepared from the following components in parts by mass: 68 to 72 parts of anhydrite, 10 to 15 parts of cement, 8 to 10 parts of stone powder, 8 to 12 parts of vitrified micro bubbles of 70 to 90 meshes, 0.5 to 1.5 parts of an accelerator, 0.17 to 0.25 part of a water-retaining agent and 0.03 to 0.08 part of a lubricant. The preparation method of the lightweight plastering mortar comprises the steps of S1, weighing the raw materials in parts by mass; and S2, sieving the anhydrite weighed in the step S1 with a 200-mesh sieve to obtain sieved anhydrite, crushing the stone powder, sieving with a 0.2 mm-sieve to obtain sieved stone powder, uniformly mixing the sieved anhydrite, the sieved stone powder and the other raw materials weighed in the step S1, stirring and mixing for 4-6 minutes, and then sub-packaging to obtain the lightweight plastering mortar. Compared with the traditional cement mortar, the lightweight plastering mortar disclosed by the invention has the advantages of higher strength, higher bonding strength, lower linear shrinkage rate, stronger water-retaining property and the like.

Description

technical field [0001] The invention relates to the field of building engineering materials, in particular to a lightweight plastering mortar and a preparation method thereof. Background technique [0002] With the rapid development of my country's construction industry and building materials industry, the demand for gypsum is increasing. At present, almost all plaster cementitious materials and products except chemical gypsum in my country are made of natural dihydrate gypsum, which has formed the basic system of my country's construction gypsum industry and has become an important part of my country's new building materials. The gypsum reserves in my country are very large, and the ore reserves of anhydrite deposits account for about 60%. [0003] Natural anhydrite is harder than natural dihydrate gypsum, but its hydration rate is slower, the setting time is longer, the chemical activity is poor, and the strength is low. For a long time, the research on anhydrite has pro...
