Because cracks are the main problem of mass concrete, this paper investigates an experimental study on effect polypropylene microfiber (PPMFs) self -repair behavior through microstructure, workability, physical, and mechanical properties concrete. PPMFs with a diameter 18 µm add in different percentages (0, 0.5, 1 1.5) % cement weight. Where prepared mixture ratio was (1:2:4.8) water-cement (W/...

Autogenous self-healing of water retaining concrete structures is included in Eurocode 1992-3 as a possibility to heal cracks up width 200 μm without additional repair. In this scenario flow through crack should result progressive closure the fracture, mainly due CaCO 3 precipitation, when certain hydraulic gradients are met, pH > 5.5 and concentration CO 2 remains < 40 mg*L -1 . The mate...
