本文通过对采用两种不同配合比的混凝土分别与老混凝土进行粘结,同条件养护一定龄期后进行劈裂抗拉强度试验,发现不同界面处理方式、不同配合比均对粘结强度有一定的影响,理论分析影响粘结性能的影响因素和作用机理,对工程建设和使用过程中的混凝土修补具有指导意义。
In this paper, two kinds of concrete with different mixing ratio were respectively bonded with the old concrete, the same conditions for a certain age after cleavage tensile strength test and found that different interface treatment, the different mix are bound to a certain strength The theoretical analysis of the influencing factors and mechanism of the bonding performance is of guiding significance to the concrete repair in the construction and use of the project.
