【 摘 要 】
In this paper, the flexural performances of reactive powder concrete beams with different admixtures are studied by the finite element analysis. The paper analyzes the cracking loads, the yield loads, the mid-span deflections and the equivalent stress cloud charts of reactive powder concrete beams. The results show that the different influence of admixtures on flexural performances of RPC beam is as follows: fly ash> ganister sand> powder mixed with fly ash and quartz powder> quartz powder, the influence of admixture content on flexural performance of RPC beams is larger. When the content of fly ash is 40%, the flexural performance of reactive powder concrete beam is better. By the finite element analysis, the formulas on cross-section flexural capacity of RPC beams with different admixtures are deduced.
