为了制各自流平性能良好的水泥基砂浆,本文研究了不同消泡剂种类及添加量对水泥基砂浆表观形貌的影响。选择消泡效果最佳、与减水剂相容性最好的1009型消泡剂,考察其不同添加量与水泥砂浆流动度和流动速度的关系。结果表明:相对于水泥质量,当1009型消泡剂添加量为1.2%时,水泥砂浆砂浆流动速度最大,即黏度最小;当1009型消泡剂添加量为0.9%时,消泡效果较好且水泥砂浆流动度最大,自流平性能最好。
In order to make the cementitious mortar with good leveling performance, the effects of different defoamer types and addition amounts on the apparent morphology of cementitious mortar were studied. Select the best defoaming effect, the best compatibility with the superplasticizer 1009 defoamer to examine the different amount of cement mortar fluidity and mobility relationship. The results show that when the amount of 1009 defoamer is 1.2%, the flow rate of cement mortar is the lowest, that is, the viscosity is the lowest. When the dosage of 1009 defoamer is 0.9%, the defoaming effect is better And the highest degree of fluidity of cement mortar, self-leveling the best performance.
