MRT复合防冻剂是由山西省万荣县荣河城东化工厂与武汉工业大学北京研究生部、秦皇岛第二建筑公司共同研制的,并于1988年9月通过技术鉴定。该防冻剂是由防冻、减水、早强、防锈等材料复合而成,具有抗冻性强、混凝土早强、减水、阻锈耐久性高、使用方便、节省投资等特点。适用于0℃～-35℃条件下的普通硅酸盐水泥、矿渣硅酸盐水泥和火山灰水泥配制的混凝土施工。一、主要技术指标和性能1.P H值:约7。
MRT compound antifreeze was jointly developed by Ronghe Chengdong Chemical Plant of Wanrong County, Shanxi Province, Beijing Graduate School of Wuhan University of Technology and Qinhuangdao No. 2 Construction Company, and passed technical appraisal in September 1988. The antifreeze is made of a combination of antifreeze, water reduction, early strength, rust prevention and other materials, and has the characteristics of strong frost resistance, early strength of concrete, reduced water, high rust resistance, easy use, and saving investment. It is suitable for the concrete construction of ordinary portland cement, slag portland cement and pozzolanic cement under the conditions of 0°C～-35°C. First, the main technical indicators and performance 1. P H value: about 7.
