冻融环境下引气剂对钢筋与混凝土黏结性能影响的试验研究
The Experimental Research on the Effect of Air-entraining Agent to the BondingPerformance of Reinforcement and Concrete under the Environment of Freeze-thaw
摘要
Abstract
In this article,the experimental study on the deterioration of bonding performance between reinforcement and concrete structures under freeze-thaw condition is carried out.A total of 9 sets of reinforced concrete specimens are prepared by using air entraining agent and freezing and thawing cycles as variable factors.The rapid freeze-thaw test and the method of reinforcement pull-out are used to study the bonding stress and slippage on the bonding performance of reinforcement and concrete with different dosages of air-entraining agent under freeze-thaw environment,and to make a compared analysis to the influence law of bonding performance between reinforcement and concrete under freeze-thaw environment.The experimental results show that a certain amount of air-entraining agent can alleviate the freeze-thaw damage of the specimen,and improve the bonding performance of the reinforcement and concrete in the freeze-thaw environment.关键词
