我国混凝土外加剂行业最新研发进展和市场动态

The Recent Research and Market of Concrete Admixture in China

中国建筑材料联合会混凝土外加剂分会每两年开展一次全国范围的混凝土外加剂生产情况大调查,其目的是掌握行业最新发展动态,为制定行业发展政策提供准确依据。该调查活动已经持续十余年。最新的调查数据表明:2017年我国混凝土外加剂总产量达到1 399万t,与2015年的1 380.36万t相比,略有增长;外加剂行业结构优化调整的效果十分明显,新型碳4聚醚、聚羧酸高性能减水剂、液体无碱速凝剂、新型高分子类引气剂等性能更加优良产品的占比继续增加;外加剂企业利用股市资本,规模化发展,行业集中度也在逐步提高。

In order to grasp the latest developments in the concrete admixture industry and provide a valid basis for the formulation of industry development policy, a nationwide production survey has been carried out by the Concrete Admixture Branch of China Building Materials Federation every two years in the past ten years. The latest investigation data show that the total output of concrete admixtures in China reached 13.99 million tons in 2017, a slight increase compared with 13.803 6 million tons in 2015. The effect of industrial structure optimization and adjustment was significant, the proportion of products with better performance continues to increase, such as new type carbon-4 polyether monomer, polycarboxylates high performance water-reducing admixture, liquid alkali-free accelerator, polymer type air- entraining agent. Admixture enterprises utilized the stock market capital to make the company gradually become large- scale, so the market concentration rate was gradually increasing.
