Abstract

The invention belongs to the field of building materials and particularly relates to thin-layer anti-crack masonry mortar prepared from granite stone powder. The mortar is prepared from the following raw materials in weight fraction: 40 to 60% of granite stone powder, 18% to 30% of cement, 15% to 25% of superfine mineral powder, 4% to 6% of quick lime, 2 to 5% of modified halloysite toughening material, 0.5 to 1% of polymer gelatin power, 0.03 to 0.05% of calcium chloride and 0.02 to 0.04% of high-efficiency slushing agent, wherein the sum of weight fraction of all the materials is 100%. The mortar has the advantages of high water retention, strong cohesiveness, good construction performance and the like, is especially suitable for dry-method thin-layer construction of high-precision autoclaved aerated cement mortar building blocks and can greatly improve whole performance of a wall body and flatness of a wall body base layer.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a crack-resistant thin-layer masonry mortar prepared by using granite stone powder. Background technique [0002] With the development of the construction stone processing industry, my country has become the world's largest stone production, consumption and export country, and the waste stone powder generated during stone mining and processing is also increasing and piled up into mountains, causing serious environmental pollution problems. At the same time, the reverse Restricting the sustainable development of the stone industry. Regarding the comprehensive utilization of waste stone powder, there have been many studies at home and abroad, mainly on the use of waste stone powder to make ceramics, plates, coatings, and stone powder bricks (Liang Yueqing, Turning waste stone powder into new building materials [J]. Fujian Building Materials, 2006 (1):9-11.), but there ...
