自上世纪80年代起,27种不同的针对聚合物水泥混凝土(PCC)、环氧树脂混凝土(EC)、水泥混凝土(CC)以及喷射混凝土的混凝土修护系统,在特别研制的试验模块中开始接受大气曝露试验,长达二十年的观测所取得的结果均证明了当时混凝土建筑修护规范指标的有效性,尤其使企业了解到,虽然混凝土表面并不负荷压力,但在减少混凝土覆盖量的同时以丙烯酸树脂为原料适当涂抹于混凝土表面能够给混凝土带来至少长达20年的保护。 Since the 1980s, 27 different concrete repair systems for polymer cement concrete (PCC), epoxy concrete (EC), cement concrete (CC) and shotcrete have been started in specially developed test modules Acceptance of atmospheric exposure test, the results of 20 years of observation have proved the validity of concrete construction repair specifications at that time, especially for enterprises to understand that although the concrete surface is not under load pressure, but in reducing the amount of concrete coverage At the same time, the proper application of acrylic resin as raw material to the concrete surface can bring concrete protection for at least 20 years.
