摘要
采用体积测量和长度测量相结合的试验手段,对高性能水泥基材料的自收缩变形规律进行了分阶段、全过程的研究分析,研究了矿物掺合料的种类(粉煤灰和磨细矿渣)、掺入比以及细度对自收缩的影响。结合毛细管张力理论,探讨了粉煤灰和磨细矿渣对自收缩的影响机理。
The whole-course of autogenous shrinkage deformation of high performance cement based materials was in vestigated by stages with the combining of volume measurement and length measurement. The effects of the type of mineral admixtures, including fly ash and ground blast furnace slag, addition rate and fineness on the autogenous shrinkage were studied. The mechanism was discussed on the basis of capillary tension theory.
