Abstract

The invention discloses impermeable and anti-cracking plastering mortar. The plastering mortar comprises a main body material and additives, wherein the main body material is prepared from 30-40wt% of cement, 45-55wt% of quartz sands and the balance of pulverized fuel ash; based on the main body material, the additives comprise the following components 2-3kg / ton of hydroxypropyl methyl cellulose, 3-4kg / ton of wood fiber, 0.5-1.5kg / ton of polyvinyl alcohol, 20-30kg / ton of ash-calcium and 6-10kg / ton of redispersible powder. The mortar prepared from the raw materials has good anti-cracking performance to prevent hollowing, can be easily implemented to guarantee flat wall surface after implementation, and has good impermeable performance to greatly reduce water seepage of the wall body.

Description

technical field [0001] The invention relates to a building material, in particular to an anti-seepage and anti-crack plastering mortar. Background technique [0002] With the continuous development of the construction industry, the quality requirements of the project are also getting higher and higher. Seepage and crack resistance is a very important and urgent problem to be solved. The use of waterproof mortar is the most important measure, and the addition of admixtures is the most basic means to improve the anti-seepage ability of the mortar. Adding a certain amount of fiber and waterproofing agent to the mortar can meet the increasing requirements for anti-seepage and crack resistance, and can also significantly improve the durability of the mortar. [0003] The invention patent with the publication number CN102190467A discloses an anti-seepage and anti-cracking dry-mixed mortar. Its components and mass percentages include: 20-90% cement, 2-40% barium ore, the barium or...
