补偿收缩混凝土在某综合楼地下室工程中的应用

Application of the shrinkage-compensating concrete in some union building basement

文章介绍了补偿收缩混凝土在江苏省农村信用社联合社综合楼地下室工程中的应用情况。以补偿收缩混凝土限制膨胀率为目标,通过理论分析、实验室试验和现场抽样检测证实了在复杂施工条件下,高效膨胀剂的掺加可有效补偿混凝土自收缩、温度收缩和干燥收缩等,降低结构开裂风险。

Application of the shrinkage-compensating concrete in Jiangsu province rural credit union buildingbasement was introduced in this paper. With the goal of enough limited expansion rate of shrinkage-compensating concrete and consideration to the workability, it was confirmed that the efficient expansion agentcould compensate the autogenous shrinkage, temperature shrinkage and drying shrinkage of concrete effectivelyand reduce structure cracking risk under complicated constriction conditions through theoretical analysis,laboratory test and field sampling test. Favorable engi- neering effect was achieved.
