The invention discloses quick-acting setting cement mortar which is characterized by being prepared from the following raw materials in parts by weight: 80-120 parts of cement, 3-7 parts of wood wool fiber, 5-15 parts of cellulose, 3-8 parts of a quick-acting coagulant, 15-35 parts of carborundum, 25-45 parts of dry coal ash and 10-35 parts of river sand. The preparation method of the quick-acting setting cement mortar according to the claim 1 comprises the following steps: (1) adding the wood-wool fiber, the cellulose and the quick-acting coagulant into the cement, drying and sieving the filler, adding into the cement, and fully stirring in a stirrer to prepare mixed mortar dry powder; and (2) during use, transporting the mixed mortar dry powder to a construction site, adding water, carborundum, dry coal ash and river sand on site, and stirring to prepare mortar for construction. The mortar is high in bearing capacity and longer in service life. The anti-freezing effect is better than that of ordinary cement mortar, the conventional cement mortar cannot be used for construction at the temperature of-3 DEG C, and the mortar can still be used for normal construction at the temperature of-7 DEG C.
本发明公开一种速效凝固水泥砂浆，其特征在于：由如下重量配比的原料制成：水泥80‑120份，木丝纤维3‑7份，纤维素5‑15份，速效凝固剂3‑8份，金刚砂15‑35份，干煤灰25‑45份，河沙10‑35份。一种权利要求1所述的速效凝固水泥砂浆的制备方法，包括如下步骤：(1)将木丝纤维、纤维素、速效凝固剂加入水泥中，填充剂进行烘干过筛后加入水泥中，在搅拌器中进行充分的搅拌，制成混合砂浆干粉；(2)使用时将混合砂浆干粉运输到施工现场，现场加水、金刚砂、干煤灰、河沙搅拌制成砂浆用于施工。该砂浆承重力强，使用寿命更长。抗冻效果较平常水泥砂浆效果更好，常规的水泥砂浆在‑3℃时便不能施工，本砂浆在‑7℃时仍可以正常施工。
