Quick-hardening and quick-setting autoclaved aerated concrete block repair mortar
The invention discloses quick-hardening and quick-setting autoclaved aerated concrete block repair mortar, and particularly relates to the technical field of building materials, the repair mortar is composed of gypsum mortar, a quick-hardening agent, an air entraining agent, a polymer additive and a thickening time control agent, wherein the sum of the weight percentages of the gypsum mortar, the rapid hardening agent, the air entraining agent, the polymer additive and the thickening time control agent is 100%: 63%-75% of the gypsum mortar, 15%-20% of the rapid hardening agent, 0.05%-0.1% of the air entraining agent, 4.5%-5.2% of the polymer additive and 3.5%-4.8% of the thickening time control agent. According to the quick-hardening and quick-setting autoclaved aerated concrete block repairing mortar disclosed by the invention, the prepared mortar has relatively high bonding strength, has drying density similar to that of an autoclaved aerated concrete block, has texture similar to that of the autoclaved aerated concrete block after being hardened, and has quick-hardening and quick-setting effects; and the shrinkage rate of the hardened mortar is reduced, the condition that the hardened repaired part is dried and cracked is avoided, the qualified rate of products is ensured, and resource waste is reduced.
本发明公开了一种快硬快凝蒸压加气混凝土砌块修复砂浆，具体涉及建筑材料技术领域，该修补砂浆由石膏砂浆、快硬剂、引气剂、聚合物添加剂和调凝剂组成，其中石膏砂浆、快硬剂、引气剂、聚合物添加剂和调凝剂以重量百分比之和为100％计：石膏砂浆63％‑75％，快硬剂15％‑20％，引气剂0.05％‑0.1％聚合物添加剂4.5％‑5.2％，调凝剂为3.5％‑4.8％。本发明所述的一种快硬快凝蒸压加气混凝土砌块修复砂浆，制备的砂浆具有较高的粘合强度，与蒸压加气混凝土砌块具有相似的干燥密度，硬化后具有与蒸压加气混凝土砌块相似的质感，具有快硬快凝的效果，与现有技术相比，降低了砂浆硬化后的回缩率，避免了硬化后的修复部分出现干裂的情况，保证了产品的合格率，降低了资源浪费。
