目前,砂浆微沫剂在国内已有不少品种的产品,在一些工程中应用获得了一定的效果,但在应用中反映出两方面的问题:一是掺用微沫剂的砂浆早期强度提高不大,后期强度下降;二是使用不便,市售微沫剂大多数需要用60～80℃热水溶解,现场应用比较困难。为了解决这两个问题,我们研究出一种应用方便的SW型砂浆微沫剂。 At present, mortar micro-foaming agents have many varieties of products in the country, and have achieved certain results in some projects. However, there are two problems in their application: First, the early strength of mortar mixed with micro-foaming agents has increased. Not much, the late strength decreased; Second, the use of inconvenience, the majority of commercially available micro-foam agents need to use 60 ~ 80 °C hot water dissolution, field application is more difficult. In order to solve these two problems, we have developed an easy-to-use SW mortar mortar.
