摘要
混凝土自问世以来,凭借其优异的性能,加速推进了人类社会的发展,但在人们日益增长的高质量生活需求下,混凝土性能方面的不足逐渐被暴露出来。直至今日,人们对混凝土的探索也永未止步。针对混凝土收缩及开裂的相关问题,系统阐述了自收缩、干燥收缩、塑性收缩、化学收缩、碳化收缩、温度收缩等基本概念、作用机理和测量方法,以及收缩与开裂的关系和抗裂性研究的试验方法,为相关研究人员制定合理的改善措施提供理论依据。
Since the advent of concrete,with its excellent performance,it has accelerated the development of human society.However,under the increasing demand for high-quality life,the shortage of concrete performance has gradually been exposed.Until today,people′s exploration of concrete has never stopped.Aiming at the related problems of concrete shrinkage and cracking,it systematically expounds the basic concepts,interaction mechanism and measuring method of autogenous shrinkage,drying shrinkage,plastic shrinkage,chemical shrinkage,carbonization shrinkage and temperature shrinkage,as well as the relationship between shrinkage and cracking,and the test method of crack resistance research,which provides theoretical basis for relevant researchers to formulate reasonable improvement measures.
