Mortar with high salt water resistance for air-entrapping brick
The invention discloses mortar with high salt water resistance for an air-entrapping brick. The mortar with the high salt water resistance for the air-entrapping brick is prepared from, by weight, 56% of silica sand, 10% of pulverized fuel ash, 2% of talcum powder, 2% of calcium carbonate, 2% of kaolin, 1.5% of mica powder, 12% of cement, 7% of pottery sand, 2% of calcium sulphoaluminate, 0.5% of hydroxyethyl methyl cellulose, 1.5% of fiberglass, 2.5% of redispersible latex powder, 0.5% of melamine water reducing agents and 0.5% of hydroxyethyl cellulose. According to the mortar with the high salt water resistance for the air-entrapping brick, the production technology is simple, and the cost is low; graft modification is conducted on the calcium carbonate which is dispersed in the mortar to form a dispersion system, internal stress of the mortar can be absorbed, and shrinkage settlement of the mortar can be reduced; the processed fiberglass and mica powder are added, the salt water resistance of the prepared air-entrapping brick can be effectively improved, the phenomena such as bad hardening and cracking which are caused due to the fact that the mortar is dried excessively fast, and the moisture is not enough can be effectively prevented, and the breaking strength of the air-entrapping brick can be improved.
