多组分混凝土徐变主动控制试验研究

Experimental Study on Active Creep Control of Multi-component Concrete

文章针对超高层建筑施工中存在的形变问题,开展了多组分混凝土徐变主动控制试验研究,研究了水泥净浆-砂浆-混凝土徐变相关性、不同弹性模量的工程纤维对混凝土徐变性能的影响等。通过试验研究,得出可通过改变胶凝材料品种实现徐变主动控制的方法。文章研究结果为工程施工提供了重要参考,为超高层混凝土徐变主动控制技术的研究提供了有益建议,试验研究思路可为类似工程提供参考。

In view of the deformation problems in the construction of super high-rise buildings,the experimental study on the active control of multi-component concrete creep was carried out.The creep correlation of cement paste-mortar-concrete and the influence of engineering fibers with different elastic modulus on the creep performance of concrete were studied.The experimental study found that the creep active control method can be realized by changing the variety of cementitious materials.The research results of this paper provide an important reference for engineering construction,and provide useful suggestions for the research of active creep control technology of super high-rise concrete.At the same time,the experimental research ideas can provide reference for similar projects.
