可再分散乳胶粉对抗裂抹面砂浆的影响

摘要

通过对含有不同掺量可再分散乳胶粉的抗裂抹面砂浆的试验,得出相应的抗裂抹面砂浆的拉伸粘结强度,绘制出可再分散乳胶粉掺量变化时拉伸粘结强度的变化曲线,得出了抗裂抹面砂浆的拉伸粘结强度和可再分散乳胶粉掺量的变化规律,研究结果为配制不同应用要求的抗裂抹面砂浆提供了一些基础试验数据和参考.%Through the test of the crack resistant mortar with different quantities of redispersible emulsion powder, the tensile bond strengths of crack resistant mortar and the curve of the tensile bond strengths with different quantities of redispersible emulsion powder were identified. The change rule of the tensile bond strength with the quantities of redispersible emulsion powder was researched. The results can provide some basis experimental data and suggestion for meeting crack resistant mortar with different requirements.
