把聚合物乳液掺入水泥砂浆,研究其对水泥水化作用及其它性能的影响。采用乙烯—醋酸乙烯酯共聚乳液(EVAC)、水溶性环氧(HEP)、丁苯胶乳(SBR)、聚偏二氯乙烯—丙烯酸酯共聚乳液(PVDC—AC)和丙烯酸酯乳液(AC-4001),用量热器及微机监控的方法测定上述聚合物不同掺量时水泥水化放热过程,及上述聚合物乳液改性水泥砂浆的抗拉强度、抗压强度试验结果,同时研究了聚合物乳液的掺入对水泥砂浆吸水率、抗冻融和抗渗性能的影响。
The polymer emulsion was incorporated into the cement mortar to investigate its effect on the hydration and other properties of the cement. Ethylene-vinyl acetate copolymer emulsion (EVAC), water-soluble epoxy (HEP), styrene-butadiene latex (SBR), polyvinylidene chloride-acrylate copolymer emulsion (PVDC-AC) and acrylate emulsion (AC-4001) The determination of the tensile strength and compressive strength of the above-mentioned polymer emulsion-modified cement mortar when measuring the amount of the above-mentioned polymer with different amounts of cement in the hydration process of the cement and the microcomputer monitoring method were carried out, and the polymer was studied at the same time. Effect of Incorporation of Emulsion on Water Absorptivity, Freeze-thaw Resistance and Impermeability of Cement Mortar.
