The invention discloses wear-resistant and crack-resistant cement mortar and a preparation method thereof, and belongs to the technical field of cement mortar. The wear-resistant and crack-resistant cement mortar is prepared from the following raw materials in parts by weight: 240-270 parts of cement, 20-35 parts of fly ash, 130-150 parts of river sand, 65-85 parts of gravel, 1-4 parts of polycarboxylate water reducing agent, 8-15 parts of steel fibers or functionalized steel fibers and 80-100 parts of water. The functional steel fibers are adopted in the cement mortar, so that the problem of poor dispersity of steel fibers in cement mortar can be effectively improved, the bonding stress between the steel fibers and the cement mortar can be improved, and the wear resistance and crack resistance of the cement mortar are further improved. The wear-resistant and crack-resistant cement mortar disclosed by the invention is simple in preparation method and low in production cost, has the characteristics of high cohesiveness, good wear resistance, excellent crack resistance, good durability and the like, can be applied to building surfaces such as grounds, pavements or bridge decks which need to touch external objects such as automobiles, and can prolong the service life and reduce the maintenance cost.
本发明公开了一种耐磨抗裂水泥砂浆及其制备方法，属于水泥砂浆技术领域，其中所述耐磨抗裂水泥砂浆由以下重量份原料组成：240‑270重量份水泥、20‑35重量份粉煤灰、130‑150重量份河砂、65‑85重量份碎石、1‑4重量份聚羧酸盐减水剂、8‑15重量份钢纤维或功能化钢纤维、80‑100重量份水。本发明在水泥砂浆中采用功能化钢纤维，不仅能够有效改善钢纤维在水泥砂浆中分散性差的问题，还能提高钢纤维与水泥砂浆之间的粘合应力，进而提高了水泥砂浆的耐磨抗裂性能。本发明耐磨抗裂水泥砂浆，制备方法简单、生产成本低，同时具有粘结性高、耐磨性好、抗裂性能优异、耐久性好等特点，可用于需要碰触到汽车等外界物体的地面、路面或桥面等建筑面上，延长使用寿命，减少维护成本。
