江苏江都丁伙有机化工厂研制生产的一种具有早强和减水双重功能的混凝土外加剂——FR复合早强减水剂,于1987年10月6日通过了河海大学、南京工学院等单位专家们的技术鉴定。该材料是由硫酸盐、阴离子表面活性剂等原料复合而成。在同类产品中,具有价格低廉、质量稳定、添加量小的特点,广泛应用于各种混凝土构件行业。经南京水利科学研究院测试,其减水率、抗压强度、抗冻性等指标均
A concrete admixture with the dual function of early strength and water reduction, FR composite early strength superplasticizer developed by Jiangsu Jiangdu Dinghu Organic Chemical Factory, was passed on October 6, 1987 by Hohai University and Nanjing Institute of Technology. Technical appraisals of experts in other units. The material is a composite of sulfate, anionic surfactant and other raw materials. In the same kind of product, it has the characteristics of low price, stable quality, and small addition amount, and is widely used in various concrete component industries. Tested by Nanjing Hydraulic Research Institute, its water reduction rate, compressive strength, frost resistance and other indicators
