Wet-mixed masonry mortar prepared by adopting aggregate chips
The invention discloses wet-mixed masonry mortar prepared by adopting aggregate chips. The wet-mixed masonry mortar comprises the following components in parts by weight: 18-22 parts of cement, 6-8 parts of pulverized fuel ash, 5-7 parts of mineral powder, 22-25 parts of water, 135-145 parts of aggregate chips and 0.5-2.0 parts of a mortar admixture, wherein the particle size of the aggregate chips is not more than 4.75mm; the mountain flour in the aggregate chips accounts for 2-3 percent by weight; the mortar admixture serves as a thickening agent; the thickening agent comprises the following components in parts by weight: 2-4 parts of a sulfonic acid type air entraining agent, 10-20 parts of a melamine water reducing agent, 1-3 parts of soft sugar, 1-3 parts of a water repellent, 4-6 parts of sodium carboxymethyl cellulose and 40-60 parts of sodium bentonite. The machine-made sand and river sand are replaced by residual aggregate chips after stone processing, the aggregate chips are readily available and low in price, the resources are reasonably utilized, the environmental pollution caused by waste aggregate chips is reduced, and the production cost of the mortar is reduced.
