Long-term properties and microstructure change of engineered cementitious composites subjected to high sulfate coal mine water in drying-wetting cycles

The mine water environment in underground reservoirs poses great threat to the durability of artificial concrete dams, mainly due to the coupled sulfate and drying-wetting cycles. As a novel response, application of Engineered Cementitious Composites (ECC) featured by strain-hardening characteristics and inherent crack control ability in artificial dam is proposed. The special influence of simulated high sulfate mine water and drying-wetting...
