摘要：总结了蒸养混凝土的收缩开裂、热损伤、延迟钙矾石形成三种典型损伤类型，分析了损伤作用机理。并提出了改善蒸养混凝土损伤的措施：适量掺入矿物掺合料、优化蒸养制度、合理的后续补充养护、适量掺入内养护材料SAP等。 Abstract: Three typical types of damage, namely shrinkage cracking, thermal damage, and delayed formation of ettringite in steam curing concrete are summarized. The damage mechanism is analyzed, and improvement measures for steam curing concrete damage are proposed. Moderate addition of mineral admixtures, optimization of steam curing system, reasonable subsequent supplementary curing, and appropriate addition of internal curing material SAP can all improve the damage of steam curing concrete to a certain extent.
