The invention discloses an aerated brick masonry structure paste, and belongs to the field of brickwork. The aerated brick masonry structure paste is prepared from the following substances in percentage by mass: 50 percent to 55 percent of lime powder, 35 percent to 40 percent of water, 1.1 percent to 1.3 percent of polyvinyl alcohol, 0.5 percent to 0.8 percent of hydroxypropyl methyl cellulose, 0.2 percent to 0.3 percent of dispersible latex powder and 0.1 percent to 0.2 percent of urea. The materials are fully and uniformly stirred to form paste and then packaged and sealed, the package onlyneeds to be opened for use during bricklaying, stirring labor and stirring equipment on a construction site can be saved, and labor and time are saved compared with cement mortar. The lime powder isselected from slaked lime powder or quick lime powder with the mass percent of 35%-42%, calcium carbonate can be formed by the structure paste and carbon dioxide in air after the structure paste is used, the binding force between the aerated bricks is guaranteed by combining with the polyvinyl alcohol binding agent, and the overall structural strength of the wall is improved.
本发明公开了一种加气砖砌体结构膏，它属于砌体领域，由以下质量百分比的物质组成：石灰粉50％‑55％，水35％‑40％，聚乙烯醇1.1％‑1.3％，羟丙基甲基纤维素0.5％‑0.8％，可分散性乳胶粉0.2％‑0.3％，尿素0.1％‑0.2％；上述物质充分均匀搅拌形成膏状后包装密封，砌砖时只要打开包装使用便可，可节省工地搅拌人工和搅拌设备，比水泥砂浆省工省时。本发明石灰粉选用熟石灰粉，或者采用质量百分比为35％‑42％的生石灰粉，本结构膏其使用后会与空气中二氧化碳形成碳酸钙，再结合聚乙烯醇粘结剂，保证了加气砖之间的结合力，提高了墙体整体结构强度。
