高温缓凝剂在砼工程中的应用研究

High temperature retarding admixtures for in-situ construction in concrete engineering

  • 摘要: 本文结合道路、水利水电、桥梁工程施工实例研究新型高温缓凝剂(HR)的技术性能,结果表明采用高温缓凝剂可使当前碾压砼、泵送砼在高温下施工存在的层间结合问题、坍落度损失问题得到有效解决,取得良好的技术经济效果。

     

    Abstract: Combined with construction examples in highway, hydraulic and bridge engineering,this paper studied the technical features of new type high temperature retarding admix-tures(HR). Research results revealed that the properties of interlayer bonding of roller compacted concrete, slump loss of pumping concrete in construction under high tempera- ture can be obviously improved by use of the high temperature retarder, and good technical and economic benefits had been obtained.
