摘要
用苯乙烯丙烯酸酯（ＳＡＥ）共聚乳液作为改性剂， 对水泥砂浆进行改性。通过试验考察了共聚物对水泥及水泥砂浆强度的影响。结果表明，ＳＡＥ的加入使水泥及水泥砂浆的抗折强度有明显的提高， 但抗压强度有所降低； 共聚物中单体的组成比对砂浆的强度也有很大影响。
Cement mortar is modified with styrene acrylic ester(SAE) copolymer emulsion. The effects of SAE on the strength of cement paste and cement mortar was studied. The results show that SAE significantly improves bending strength of cement paste and cement mortar but reduces their compression strength. Also, the proportion of copolymeric monomers has great effects on the strength of cement mortar.
