摘要
聚合物改性水泥砂浆的抗拉强度、粘结强度、抗渗和抗碳化性能明显优于普通水泥砂浆,适宜混凝土结构表面的补强和修补。本试验选用聚合物-丙烯酸酯共聚乳液作为水泥添加剂,分析研究了不同乳液掺量下水泥砂浆的性能,由此得出乳液掺量对水泥砂浆性能影响的规律,为此聚合物改性水泥砂浆的应用提供了理论依据。
The tensile strength, bonding strength, impervious and the anti-carbonized performance of polymer modified cement mortar surpasses the ordinary cement obviously and it is suitable the concrete structure surface makes up strong and patching. This experiment selects the Polymer-propylene diethylene glycol dinitrate copolymerization emulsion to take the cement chemical additive and studies the performance of the different emulsion to mix the quantity sewer soil mortar, from this obtains the rule of the emulsion to mix the quantity adding mortar performance influence and it provids the theory basis for this polymer modified cement mortar application.
