摘要:The efficient rapid repair for the distressed concrete pavement requires a rapid setting material that can be placed, cured, and opened to the traffic in short period. Normally, the time of the traffic open is determined by the concrete strength gain in the early hours. Meanwhile, the strength development and thermal and shrinkage properties of the concrete affect the structural and bonding performance of the repaired pavement. Type III cement and Calcium Sulfoaluminate (CSA) cement are categorized as the rapid set cement (RSC) and are the most widely used as the cementitious material for the concrete structure rapid repair. The compressive strength of the RSC concrete cylinders with different mix proportions had been tested to obtain a strength gain guide for the rapid repair construction. Coefficient of the thermal expansion and shrinkage of the concrete were experimented. The results show that the RSC cement concretes are steady and can meet the requirement of the concrete pavement repair.
