Study and Freezing Tests of Shrinkage-compensating Concrete of Port Engineering

本文试验研究了掺膨胀剂所配制的引气补偿收缩混凝土的抗冻性 ,推荐了适宜补偿收缩混凝土的抗冻性试验方法 ,指出了混凝土膨胀剂掺量在 1 2以内可配制出满足北方港工具有一定抗冻性要求的抗冻补偿收缩混凝土。

The paper introduces the study of freeze-thaw dlurability tests of air-entrained shrinkage-dompensating concrete mixing expansion agent and gives an experiment method for frost-resistance of shrinkage-compensating concrete.The testing results shows if the expension agent added in concrete is less than 12%,the shrinkage-compensating concrete with frost-resisting property can be made and it can satisfy the rpuirements of construction in north marine works of China.
