Study on Dynamic Characteristics and Micro-mechanism of Geopolymer Concrete
摘要
Abstract
In order to investigate the effect of mix proportions on the performance of geopolymer concrete(GC),a series of dynamic mechanical model tests were carried out on GC with different fly ash,slag and silica fume content ratios by using Split Hopkinson Pressure Bar(SHPB)device,and the microstructure of geopoly-mer concrete was analyzed by means of scanning electron microscope(SEM).The results show that specimens with higher slag or silica fume content under static load are easy to obtain better mechanical properties,while GC-2 specimens with 5%silica fume content and 45%slag content have the best dynamic mechanical re-sponse and high DIF strain rate sensitivity in dynamic compression test.The research results have certain ref-erence value for the mixing ratio of geopolymer concrete.关键词
