摘　　要：结合工程实例介绍使用混凝土膨胀剂配制补偿收缩混凝土 ,减少钢筋混凝土结构收缩、开裂 ,延长建筑物伸缩缝间距的经验 ,并对该技术使用条件进行了探讨并提出建议。In this article, integrating with engineering practice, there are introductions about how to apply the concrete expansion admixture to manufacture the well compensated shrink concrete,to reduce and eliminate shrinkage and cracks of R.C.structures, and above all, to lengthen the spacing distance between expansion joints in R.C. structure. Moreover, there are some discussions about how to properly apply this technology, and provided with some helpful suggestions.
