Environment-friendly anti-cracking dry-mixed plastering mortar
The invention relates to the technical field of building materials, and particularly discloses environment-friendly anti-cracking dry-mixed plastering mortar. The environment-friendly anti-cracking dry-mixed plastering mortar is prepared from the following raw materials in parts by weight: 40 to 70 parts of clinker-free ecological cementing materials, 40 to 70 parts of superfine slag powder, 50 to 90 parts of active fly ash, 5 to 20 parts of lithium silicate powder, 5 to 15 parts of anti-cracking fibers, 20 to 50 parts of hollow microspheres, 700 to 800 parts of sand, 0.2 to 0.5 part of HPMC (Hydroxy Propyl Methyl Cellulose), 0.2 to 0.8 part of thixotropic agents, 0.2 to 0.8 part of water reducing agents and 5 to 20 parts of ethylene-vinyl acetate. The plastering mortar has the advantages that slag, coal cinder and other waste solids are processed into the plastering mortar, the plastering mortar has the advantages of being high in bonding strength, good in water-retaining property, smooth in construction, free of hollowing, free of cracking and free of powder falling, the mortar material can be used after being conveyed to a construction site and stirred with water during use, and labor and materials are saved.
本发明涉及建筑材料技术领域，具体公开一种环保抗裂干混抹灰砂浆。所述环保抗裂干混抹灰砂浆由以下重量份的原料制成：无熟料生态胶凝材料40‑70份、矿渣微粉40‑70份、活性粉煤灰50‑90份、硅酸锂粉5‑20份、抗裂纤维5‑15份、空心微珠20‑50份、砂700‑800份、HPMC 0.2‑0.5份、触变剂0.2‑0.8份、减水剂0.2‑0.8份、乙烯‑醋酸乙烯5‑20份。其优点表现在：本发明利用矿渣、煤渣等废固加工成抹灰砂浆，具有粘结强度高、保水性好、施工滑爽、不空鼓、不开裂、不掉粉的优点，使用时将砂浆材料运送到施工现场加水搅拌即可使用，省工省料。
