摘要: 通过试验研究了活性粉末混凝土的基本力学性能(抗压强度、抗折强度、耐高温性能),分析了钢纤维掺量对活性粉末混凝土力学性能的影响.并应用扫描电镜,从微观上分析了钢纤维掺量对RPC强度的影响,找出合理的钢纤维掺量为1.0%.

关键词: 活性粉末;混凝土;钢纤维;抗压强度;抗折强度

Abstract: The basic mechanical properties(compressive strength,flexural strength and high temperature resistance)of reactive powder concrete were studied by experiments.The influence of the amount of steel fiber on the mechanical properties of reactive powder concrete was analyzed.The influence of the amount of steel fiber on the strength of RPC was analyzed by means of scanning electron microscopy(SEM).The reasonable dosage of steel fiber is 1%.

Key words: reactive powder;concrete;steel fiber;compressive strength;flexural strength
