Building masonry mortar formula and test method
The invention discloses a masonry mortar formula for building and a test method, the masonry mortar formula comprises 150g of cement, 748.2 g of sand, 1.8 g of hydroxypropyl methyl cellulose, 100g of fly ash, 1.8 g of hydroxypropyl methyl cellulose, 92% of a hydroxypropyl methyl cellulose pure product, 3% of dispersible latex powder, 2% of starch ether, 2% of bentonite, 1% of polyacrylamide, and the balance of water. The modified cellulose has the advantages that the water retention rate, compressive strength, bonding strength and shrinkage rate of mortar prepared from the modified cellulose conform to the numerical range of technical indexes, the water retention rate, compressive strength and bonding strength are obviously higher than the technical indexes, and the shrinkage rate is obviously lower than the technical indexes; the starch ether, the bentonite, the polyacrylamide and the dispersible rubber powder are added into the hydroxypropyl methyl cellulose, so that the water retention rate and the bonding strength are remarkably improved, the shrinkage rate is reduced, and the performance is better than that of similar products sold in the market.
本发明公开了一种建筑用砌筑砂浆配方及测试方法，水泥150g、砂子748.2g、羟丙基甲基纤维素1.8g、粉煤灰100g，羟丙基甲基纤维素1.8g由以下成分组成：羟丙基甲基纤维素纯产品92％、可分散乳胶粉3％、淀粉醚2％、膨润土2％、聚丙烯酰胺1％，本发明具有以下优点：本发明的改性纤维素制备的砂浆，保水率、抗压强度、粘结强度、收缩率均符合技术指标数值范围，且保水率、抗压强度、粘结强度显著高于技术指标，收缩率明显低于技术指标，在羟丙基甲基纤维素中加入淀粉醚、膨润土、聚丙烯酰胺和可分散胶粉，显著提高了耐保水率、粘结强度，并且降低了收缩率，比市售的同类产品性能要好。
