Light anti-cracking plastering mortar
The invention provides light anti-cracking plastering mortar, and relates to the technical field of building materials and construction. The light anti-cracking plastering mortar comprises, by weight, 20-30% of ordinary Portland cement, 20-30% of graded sand and stone, 3-15% of glazed hollow beads, 5-25% of ground calcium carbonate powder, 0.1-0.5% of modified polyoxyethylene, 0.01-0.2% of modified cellulose ester water retaining agent, 0.05-0.1% of anti-cracking fiber, 0.3-0.5% of inorganic bentonite, 0-0.01% of sodium dodecyl benzene sulfonate and 0.1-0.2% of powder shrinkage reducing (PSR) agent. By means of the light anti-cracking plastering mortar, the construction performance and crack resistance of the mortar are obviously improved; the light anti-cracking plastering mortar has good heat preservation and sound insulation effects; raw materials can be easily purchased, the production process is simple, mechanized construction is achieved, market application prospects are wide, and the light anti-cracking plastering mortar has the social significance of the refined synergism effect on building energy conservation materials.
