Fiber-Reinforced Rapid Repair Material for Concrete Pavement
The main problems of repair materials for concrete pavement are big shrinkage and weak bond etc. The rapid repair material discussed in this paper is concrete with compound early-strength admixture. Its compressive strength and flexural strength (1d) is up to 23.1MPa and 3.74MPa respectively, which meets open to traffic demand in one day. Repair materials mixed with alkali-proof glass fiber or polypropylene fiber mesh were studied. Flexural strength and interfacial bond strength increased, shrinkage value reduced when fiber was blended. The results indicate that there is a strong linear correlation between splitting strength of repair material and bond strength.
