Modified cement-based micro-expansive mortar for vertical joints and preparation method of modified cement-based micro-expansive mortar
The invention discloses modified cement-based micro-expansive mortar for a vertical joint and a preparation method of the modified cement-based micro-expansive mortar. The mortar comprises the following components in parts by mass: 650-670 parts of cement; 355 to 365 parts of limestone powder; 277 to 285 parts of water; 859 to 877 parts of sand; 53 to 53.8 parts of an expanding agent; 3.56 to 3.64 parts of a water reducing agent; 0.29 to 0.31 part of a foaming agent; 1.78 to 1.82 parts of a defoaming agent; 39 to 40 parts of polymer emulsion; 9.43 to 9.63 parts of rubber particles; and 1.42 to 1.46 parts of emulsified asphalt. The mortar material has the advantages of high fluidity, high early strength, no shrinkage or slight expansion in the hardening process, high toughness, crack resistance and the like, and the preparation method is simple and low in cost.
本发明公开了一种用于竖向接缝的改性水泥基微膨胀砂浆及其制备方法。该砂浆包括以下质量份组分：水泥650～670份；石灰石粉355～365份；水277～285份；砂859～877份；膨胀剂53～53.8份；减水剂3.56～3.64份；发泡剂0.29～0.31份；消泡剂1.78～1.82份；聚合物乳液39～40份；橡胶颗粒9.43～9.63份；乳化沥青1.42～1.46份。本发明的砂浆材料具有大流动性、较高早期强度、硬化过程中无收缩或微膨胀、高韧性、抗裂性等优点，且制备方法简单，成本低廉。
