Pouring mortar for building secondary structure
The invention discloses a pouring mortar for a secondary structure of a building. The pouring mortar is prepared from the following components in parts by weight: 25-45 parts of cement, 8 to 15 partsof fly ash, 35.5 to 63 parts of machine-made sand, 1 to 1.6 parts of a pumping agent, 1 to 1.6 parts of a shrinkage reducing agent, 0.5 to 0.9 part of hydroxypropyl methyl cellulose ether, 1 to 1.8 parts of redispersible latex powder, 0.5 to 0.9 part of sodium lignin sulfonate, 0.1 to 0.5 part of sodium gluconate and 0.5 part of starch ether. According to the invention, the pumping performance, thixotropic performance and construction performance are good, the strength is also greatly improved; the dispersible latex powder and the starch ether are added, so that cohesion of the mortar is increased, the mortar is not separated and precipitated in the construction process, and the construction speed is guaranteed.
本发明公开了一种建筑二次结构灌注砂浆，包括以下重量配比的组分：水泥25‑45份，粉煤灰8‑15份，机制砂35.5‑63份，泵送剂1‑1.6份，减缩剂1‑1.6份，羟丙基甲基纤维素醚0.5‑0.9份，可在分散性乳胶粉1‑1.8份，木质素磺酸钠0.5‑0.9份，葡萄糖酸钠0.1‑0.5份，淀粉醚0.5份。本发明具有很好的泵送性能、触变性能、施工性能，强度也得到大幅度提高；添加了可在分散性乳胶粉，淀粉醚，增加关注砂浆的内聚力，砂浆在施工过程不离析不沉淀，保证施工的速度。
