The invention provides special mortar for building floors and floating floors, which comprises the following components in parts by mass: 20-50 parts of anhydrous gypsum or hemihydrate gypsum, 5-10 parts of CaSO4 crystal reinforcing material, 3-5 parts of silicon nano reinforcing agent, 50-70 parts of graded sand, 5-10 parts of Portland cement, 0.1-0.5 part of special water reducing powder, 0.1-0.5 part of a water-retaining agent, and 0.1-0.5 part of a gypsum retarder. According to the mortar special for the building floors and the floating floors, the problem that existing cement mortar is prone to cracking is solved by using semi-hydrated gypsum or anhydrous gypsum; the mortar can be used for the building floors and the floating floors, and due to the fact that the CaSO4 crystal reinforcing material and the silicon nanometer reinforcing agent are added into the mortar special for the building floors and the floating floors, the cement mortar is not prone to cracking. After one year,the compression strength acceptance conforms to the specification. The problem of poor water resistance of the existing mortar special for building floors and floating floors is solved, and the mortaris not easy to hydrolyze after being soaked in water.
本发明提供了一种建筑楼地面和浮筑楼面专用砂浆，所述建筑楼地面和浮筑楼面专用砂浆各组分的质量份数为：无水石膏或者半水石膏20‑50份，CaSO4晶体增强材料5‑10份，硅纳米增强剂3‑5份，级配砂50‑70份，硅酸盐水泥5‑10份，专用减水粉剂0.1‑0.5份，保水剂0.1‑0.5份，石膏缓凝剂0.1‑0.5份。本发明的建筑楼地面和浮筑楼面专用砂浆，通过使用半水石膏或者无水石膏，从而解决现有水泥砂浆容易开裂问题，可以用于建筑楼地面和浮筑楼面，所述建筑楼地面和浮筑楼面专用砂浆因为加入CaSO4晶体增强材料和硅纳米增强剂，在一年之后的压缩强度验收符合规范，同时解决了现有建筑楼地面和浮筑楼面专用砂浆耐水性差的问题，泡水不易水解。
