摘要: Abstract In this study, an innovative permeability device allowing measurement simultaneously to loading was used investigate the water and self-healing of reinforced concrete. The experimental conditions focused on normal strength concrete (NSC) fiber (FRC) tie specimens under static constant tensile loadings. Crack pattern crack openings same loadings were measured companion specimens. Experimental results emphasized positive contribution fibers durability Under loading, FRC 60% 70% less permeable than NSC at level stress in reinforcement. After 6 days showed greater capacity with a reduction penetration comparison 50% for NSC. main cause formation calcium carbonate (CaCO 3 ).
