LD 型砼防冻剂是尿素复合型产品,无毒,不含有氯盐,对钢筋无锈蚀作用,适用于工业与民用建筑、道路桥梁及水工建筑等钢筋砼工程的冬期施工。1985年冬季已用于辽宁省150多个工程项目中,28天强度可达设计标号50%左右(-20℃的条件下),最终强度可达设计标号,砼性能优于基准砼。而且使用方便,降低冬季施工费用,现已在施工单位推广应用。
LD type antimony antifreeze is a urea compound product, non-toxic, does not contain chlorine salt, has no rust effect on steel bars, and is suitable for winter construction of reinforced concrete projects such as industrial and civil buildings, roads, bridges and hydraulic construction. In the winter of 1985, it has been used in more than 150 projects in Liaoning Province. The strength in 28 days can reach 50% of the design number (under the condition of -20°C). The final strength can reach the design number, and the performance is better than the benchmark. Moreover, it is easy to use and reduces winter construction costs. It is now widely used in construction units.
