Quick-setting early-strength mortar and preparation method thereof
The invention relates to the field of building materials, and particularly discloses quick-setting early-strength mortar and a preparation method thereof, and the quick-setting early-strength mortar is prepared from the following raw materials in parts by weight: 350-420 parts of cement, 800-900 parts of sand, 10-20 parts of fly ash, 12-22 parts of composite fiber, 8-15 parts of coagulant, 8-15 parts of air entraining agent, 8-16 parts of water reducing agent and 160-220 parts of water. The cement is composed of magnesite cement and sulphoaluminate cement in a weight ratio of 2: 1; the composite fiber is composed of basalt fiber and modified bamboo charcoal fiber in a weight ratio of 3: 2; the preparation method comprises the following steps: weighing cement, sand, fly ash and water, and stirring to obtain a mixture; adding composite fibers and a water reducing agent, and stirring to obtain a mixture; adding an air entraining agent and a coagulant, and stirring to obtain quick-setting early-strength mortar. The method has the advantages of improving the early strength of mortar and shortening the mortar setting time.
本申请涉及建筑材料领域，具体公开了一种速凝早强砂浆及其制备方法，一种速凝早强砂浆，所述速凝早强砂浆由包含以下重量份的原料制成：水泥350‑420份、砂800‑900份、粉煤灰10‑20份、复合纤维12‑22份、促凝剂8‑15份、引气剂8‑15份、减水剂8‑16份、水160‑220份；水泥由重量比2:1的菱镁水泥和硫铝酸盐水泥组成；复合纤维由重量比为3:2的玄武岩纤维和改性竹炭纤维组成；其制备方法为：称取水泥、砂、粉煤灰、水搅拌后制得混合物；添加复合纤维、减水剂搅拌后制得混合料；添加引气剂、促凝剂搅拌后制得速凝早强砂浆；具有提高砂浆早期强度和缩短砂浆凝结时间的优点。
