The invention relates to dry-mixed masonry mortar, belongs to the technical field of building materials, and provides the following technical scheme for solving the problems that a masonry mortar filling layer is relatively low in water retention rate and adhesion degree. The dry-mixed masonry mortar is prepared from the following raw materials in parts by weight: 10-25 parts of cement, 63-75 parts of sand, 5-10 parts of coal ash, 10-20 parts of slag, 0.5-1.2 parts of redispersible latex powder, 0.1-0.15 part of a water-retaining agent, 0.01-0.015 part of starch ether and 0.15-0.22 part of a composite additive. The composite additive comprises sodium dodecyl benzene sulfonate, calcium formate and lithium stearate in a weight ratio of (0.03-0.07): (0.6-1): (0.12-0.28). The dry-mixed masonrymortar has the advantages of good water-retaining property and bonding strength.
本申请涉及一种干混砌筑砂浆，属于建筑材料技术领域，针对砌筑砂浆填充层的保水率和粘结度较低的问题提供以下技术方案，本申请的技术要点包括以重量份数计，其原料包括：水泥10‑25份、砂63‑75份、粉煤灰5‑10份、矿渣10‑20份、可再分散性乳胶粉0.5‑1.2份、保水剂0.1‑0.15份、淀粉醚0.01‑0.015份、复合添加剂0.15‑0.22份；所述复合添加剂包含重量比为(0.03‑0.07)：(0.6‑1)：(0.12‑0.28)的十二烷基苯磺酸钠、甲酸钙、硬脂酸锂。本申请具有良好保水性和粘结强度的优点。
