具有减缩功能的混凝土水分蒸发抑制剂及其制备方法
摘要：
本发明公开了一种具有减缩功能的混凝土水分蒸发抑制剂及其制备方法，该抑制剂由以下组分按重量比配置而成：两亲性化合物0.1%-10%、具有减少混凝土收缩功能的非离子表面活性剂0.2%-5%、阴离子表面活性剂0.2%-5%、余量为水。本发明利用具有减少混凝土收缩功能的非离子乳化剂和阴离子乳化剂协同作用，制备得到稳定的两亲性化合物乳液。将本发明应用到塑性阶段混凝土表面，不仅能有效降低塑性阶段混凝土的水分蒸发（最高可减少混凝土塑性阶段水分蒸发80%以上），同时能够有效减少硬化混凝土的收缩（最高可减少收缩20%）。本发明具有制备工艺简单，性能稳定，现场使用方便等优点。
摘要（英）：

The invention discloses a concrete water evaporation inhibitor with a shrinkage function and a preparation method thereof. The inhibitor is prepared from the following components in percentage by weight: 0.1-10 percent of an amphiphilic compound, 0.2-5 percent of a non-ionic surfactant with a concrete shrinkage reducing function, 0.2-5 percent of an anionic surfactant and the balance of water. A stable amphiphilic compound emulsion is prepared under the synergic action of a nonionic emulsifier having a concrete shrinkage reducing function and an anionic emulsifier. When the inhibitor is applied to a plastic stage concrete surface, the water evaporation of plastic stage concrete can be reduced effectively (the water evaporation of plastic stage concrete can be reduced by over 80 percent in maximum), and the shrinkage of hardened concrete can be effectively reduced simultaneously (the shrinkage can be reduced by 20 percent in maximum). The concrete water evaporation inhibitor has the advantages of simple preparation process, stable performance, convenience for field use, and the like.
