现有聚合物水泥防水砂浆硬化时间长(达8h以上),硬化后易产生裂纹,而且与混凝土被涂面的粘结力差。针对这些技术问题,日本电气化学工业公司最近研制成功一种快硬彩色聚合物水泥防水砂浆。该防水砂浆不仅具有快硬性,可任意着色,而且施工性好,富有弹性,强度高,粘附力强,无翘曲,不 The existing polymer cement waterproof mortar hardening a long time (up to 8h), easy to crack after hardening, and with the concrete surface is coated with poor adhesion. In response to these technical problems, Nippon Electrochemical Industrial Corporation recently developed a fast-hardening colored polymer cement waterproof mortar. The waterproof mortar not only has fast hardening, can be colored, and good construction, flexible, high strength, strong adhesion, no warp, no
