FDN于1978年通过省级技术鉴定,获冶金部及广东省“优秀科技成果奖”。1980年由国家建工总局定点扩建,现已达2000吨/年,成为我国最早的专业外加剂厂。该厂产品于1983年首家进入国际市场,1985年率先获省优质产品奖。现FDN、FFT及系列产品FDN—S、FDN(R)、FDN-HF、FDN-M500、FDN-M500(R)、FDN-M100以及CFR-H、CR1、 CR3等产品,己在全国27个省、市及港、澳、东南亚等地六百多万米~3的各种混凝土工程及水泥制品上广泛使用。工程实例说明,它们是提高混凝土强度和工程质
FDN passed the provincial technical appraisal in 1978 and was awarded the “Outstanding Scientific and Technological Achievement Award” by the Ministry of Metallurgy and Guangdong Province. In 1980, it was designated by the State Administration of Industry and Construction, which has reached 2,000 tons/year and became China’s earliest professional admixture plant. The plant’s first product entered the international market in 1983 and was awarded the Provincial High Quality Product Award in 1985. Now FDN-S, FDN(R), FDN-HF, FDN-M500, FDN-M500(R), FDN-M100, and CFR-H, CR1, CR3 and other products have been implemented in FDN-S, FFT and series products. It is widely used in various concrete projects and cement products in provinces, cities, and in Hong Kong, Macao, and Southeast Asia, with more than six million meters. Project examples show that they are to improve concrete strength and engineering quality
