蒸汽养生工艺下混凝土收缩徐变性能研究
Study on the Shrinkage and Creep Properties of Concrete under Steam Curing Process
摘要
Abstract
By setting three parameters including different curing conditions,constant temperature curing time,and steam curing static stop time,compressive strength,shrinkage,and creep tests are conducted to analyze the mechanical properties,shrinkage properties,and creep properties of concrete under different steam curing regimes.The experimental results show that steam curing can achieve a certain compressive strength of concrete within a short curing period,and change the pore structure,producing more connected pores and micro cracks,thereby improving the early shrinkage rate.The concrete cured by steam with a constant temperature of 55℃and a static stop time of 8 hours has the best shrinkage and creep properties,providing reference for engineering practice.关键词
