聚羧酸高性能减水剂在高速铁路高性能混凝土的试验与应用

Test and application of polycarboxylates high performance water-reducing admixture on high performance concret in high speed railway engineering

介绍了聚羧酸KJ-JS高性能减水剂的主要性能,对其在C20～C100高性能混凝土中的配合比、强度与部分耐久性等试验,以及在高速铁路武广客运专线、新广州火车站与温福铁路白马河桥等路桥工程50万m3多C15～C50HPC的工程应用实例,对高性能减水剂在客运专线与其他重大工程的高性能混凝土的配制与应用具有一定的参考价值。

The main performance of polycarboxylates KJ-JS high performance water-reducing admixture and the formula, strength, durability of C20-C100 high performance concrete （HPC） is recommended.The KJ-JS has already succeeded in the application in highrailway engineering for 500 000 m^3 C 15～C50HPC, such as WuGuang HighRailway Line, Guangzhou New Station and the Bridge of BaiMa River of WenFu Railway. According to the engineering experiences,it has some reference value for the high speed railway and others important engineering HPC which used the high performance water-reducing admixture.
