摘要
Abstract
The early shrinkage and early flat restraint cracking experiments of concrete were designed to study the crack resistance and shrinkage-reducing performance of high strength and high performance concrete in steel plate concrete composite shear wall.Four kinds of conditions were considered in the experiment,such as adding expansive agent,internal curing agent,steel fiber and the mixture of expansive agent and internal curing agent.The results show that the early shrinkage of concrete can be reduced by adding expansive agent, internal curing agent,steel fiber and the mixture of expansive agent and internal curing agent.And for the mixture of expansive agent and internal curing agent,it significantly improves the expansion effect of the expansive agent,so that the expansion strain and the expansion time of the concrete are increased,and the 28 d shrinkage is reduced by 87.6%.It also makes the concrete early cracking time delay,the crack width and number are significantly reduced.These results are good references for the the control of the early crack of steel plate concrete composite shear wall.关键词
