The invention relates to the technical field of mortar preparation, and discloses masonry mortar for autoclaved silicate bricks, which is prepared from the following components in parts by weight: 350 to 380 parts of silicate cement, 150 to 200 parts of slag admixture, 1050 to 1140 parts of fine aggregate, 2 to 2.5 parts of chemical admixture and a proper amount of water. The masonry mortar is composed of Portland cement, a slag admixture, fine aggregate, a chemical additive and a proper amount of water. The slag admixture is composed of blast furnace slag, fly ash, lime, red mud, phosphorus slag and ardealite, the chemical admixture is composed of a tea sulfonic acid formaldehyde condensate, dispersible latex powder, an organosilicon defoaming agent, hydroxyethyl cellulose ether and hydroxypropyl methyl cellulose, and the prepared masonry mortar not only has good strength increase, but also has good freezing resistance and waterproofness; the concrete has good compressive strength, bonding strength, water-retaining property, workability and workability; the compactness is good; the freezing resistance is excellent.
本发明涉及砂浆制备技术领域，公开了一种蒸压硅酸盐砖用砌筑砂浆，硅酸盐砖用砌筑砂浆，按重量份组成如下：350～380份硅酸盐水泥、150～200份矿渣掺合料、1050～1140份细集料、2～2.5份化学外加剂以及适量水。本发明的砌筑砂浆由硅酸盐水泥、矿渣掺合料、细集料、化学外加剂以及适量水组成；矿渣掺合料由高炉矿渣、粉煤灰、石灰、赤泥、磷渣和磷石膏组成，化学外加剂由茶磺酸甲醛缩合物、可分散乳胶粉、有机硅类消泡剂、羟乙基纤维素醚和羟丙基甲基纤维素组成，其制备的砌筑砂浆不仅强度增长良好，且具有较好的抗冻性和防水性；并具有良好的抗压强度、粘结强度、保水性、和易性以及工作性；密实度较好；且具有优异的抗冻性。
