Cement mortar and preparation method thereof
The invention discloses cement mortar and a preparation method thereof, and the cement mortar is prepared from the following raw materials in parts by weight: 280-330 parts of ISO standard sand, 70-90 parts of cement, 16-25 parts of fly ash, 40-60 parts of water, 0.025-0.075 part of nano aluminum nitride, 5-12 parts of spunlace non-woven fabric/melt-blown cloth fiber, 0.03-0.08 part of a water reducing agent and 0.02-0.05 part of a defoaming agent. The nano aluminum nitride doped non-woven fabric fiber cement mortar material belongs to high-strength and high-durability cement mortar, has excellent mechanical properties, can enhance the mechanical properties such as breaking strength and compressive strength of a cement-based material, and has great significance in prolonging the service life of the cement-based material; the raw materials are wide in source, non-toxic, harmless, low in price and simple in preparation process, and have good social and economic benefits.
本申请公开了一种水泥胶砂及其制备方法，以重量份计，由以下原料制成：ISO标准砂280～330份，水泥70～90份，粉煤灰16～25份，水40～60份，纳米氮化铝0.025～0.075份，水刺无纺布/熔喷布纤维5～12份，减水剂0.03～0.08份，消泡剂0.02～0.05份。申请的纳米氮化铝掺杂无纺布纤维水泥胶砂材料属于高强高耐久的水泥胶砂，力学性能优良，可以增强水泥基材料抗折强度、抗压强度等力学性能，对延长水泥基材料使用寿命具有重大意义；本申请原材料来源广泛、无毒无害、价格低廉、制备工艺简单，具有良好的社会、经济效益。
