中文摘要:过大的自收缩是造成混凝土早期开裂的主要因素之一,防治混凝土早期开裂对提高混凝土的耐久性至关重要,目前掺入矿物掺合料是减小混凝土自收缩的重要措施。介绍了水泥基材料自收缩理论,然后对比、分析和总结了不同矿物掺合料种类、掺量、细度、掺入方式和水胶比对不同龄期水泥基材料自收缩的影响,同时探究了其作用机理,对未来的相关研究和应用提出了展望。
外文摘要:Excessive autogenous shrinkage is one of the main factors that cause early concrete cracking.The preventment of early concrete cracking is very important to improve the durability of concrete.At present,the addition of mineral admixtures is an important measure to reduce the autogenous shrinkage of concrete.It introduces the theory of autogenous shrinkage of cement-based materials,and then compares,analyzes and summarizes the influence of different mineral admixture types,contents,fineness,mixing method and water-binder ratio on autogenous shrinkage of cement-based materials at different ages.The mechanism of action is explored,and the prospects for future related research and applications are put forward.
