一种具有国际先进水平的防裂型FS混凝土防水剂,已由北京利力新技术开发公司研制成功。这种防水剂不含氯盐,对钢筋无锈蚀影响。将其掺入混凝土(砂浆)拌合物中,可提高硬化后的混凝土的抗渗性、抗裂性和强度,并可减少用水,节约水泥。据测定,它的减水率为5～10%,含气 An anti-cracking FS concrete waterproofing agent with international advanced level has been successfully developed by Beijing Lili New Technology Development Company. This water repellent does not contain chlorine salts and has no rust effect on the rebar. Adding it to a concrete (mortar) mix improves the impermeability, crack resistance, and strength of the hardened concrete, reduces water use, and saves cement. According to the determination, its water reduction rate is 5 to 10%, with gas
