再生橡胶沥青防水涂料使用至今已有七年之久,全国施工面积约达一千五百万平方米。这种防水材料比纯沥青类防水材料有一定的优越性,但也存在着一些缺陷,特别是材料的抗拉强度低,抗裂性能差(抗拉强度为3kg/cm~2,抗裂性为0.2mm)等。只能适应砼基层的微裂,对于较大的裂缝发生和扩展,则无法承受。容 It has been seven years since the reclaimed rubber bituminous waterproof coating was used. The country’s construction area is about 15 million square meters. This type of waterproof material has certain advantages over pure bituminous type waterproof materials, but there are also some defects, especially the low tensile strength of the material, poor crack resistance (tensile strength of 3kg/cm~2, crack resistance 0.2mm) and so on. It can only adapt to the microcracks in the base layer, and it cannot withstand the occurrence and expansion of larger cracks. Content
