| Abstract: | The early - age concrete shrinkage deformation is the main reason to produce the non - load cracks of concrete structure. The reason for concrete non - load cracking and shrinkage mechanism are simply outlined in this study. The research and development on shrinkage reducing admixture for concrete are chiefly accounted. And the chemical structure, component and content of SRA are also given in this article. |

| Keywords: | concrete shrinkage cracks surface tension shrinkage reducing admixture |
