Additive for improving cement mortar performance
The invention relates to the technical field of building materials, in particular to an additive for improving cement mortar performance. The additive comprises 45%-55% of grade I coal ash, 1%-20% of an air entraining agent, 10%-15% of a microcrystal swelling agent, 15%-25% of an alkaline excitation agent, 3%-4% of a water retaining agent, 10%-50% of calcium carbonate, 2%-6% of sodium dodecyl sulfate, 2%-10% of hydroxymethyl cellulose, 1%-10% of polyvinyl alcohol and 10%-40% of superfine slag powder. According to the provided additive, defects of high probability of cracking, hollowing, shedding, bubbling and the like of a wall are overcome, the problem of mortar workability is solved, and the performance is effectively improved.
