新老混凝土粘结强度的影响因素分析

新地第混凝土粘结是工程施工与老化病害结构修补补强中经常面临的一个问题。目前，们们对老老混凝土粘结的机理和力学性能还缺乏足够的了解，由于粘结面破坏造成的结构功能嫁化甚至工程事故也时有发生。鉴于此，在对影响新老混缔造占结强度的因素进行试验研究的基础上，采用方差分析法对有关因素进行了分析，结果表明，粘结面的处理方式、粗糙度及新混凝土的配合比对粘结强度影响较大。

Analysis of Factors Influencing the Binding Strength of New and Used Concrete

Binding of new and used concrete is a issue often facing to project implementation and old and poor structure maintenance. At present, there is no enough knowledge about the mechanism and mechanical characteristics of binding new and used concrete, and it is often happened that structure function get degenerated and even result to project disasters. In view of above mentioned facts, variance analysis method is applied to analyze relative factors on the basis of carrying out experimental study of factors influencing new and used concrete binding strength, the achievement shows that the treatment method, roughness of the binding surface and ratio of new concrete are of evident influence on binding strength.
