Causes and Control of Concrete Cracks

Abstract

The problem of concrete cracks is a practical problem that is ubiquitous and difficult to solve. In this paper, the causes of some cracks in concrete engineering are analyzed from the aspects of design, material, mix ratio, construction site maintenance and so on. According to the causes of concrete cracks, the measures to control the development of cracks are put forward in the aspects of concrete structure design, concrete material selection, mix proportion optimization and maintenance of construction site. According to the relevant literature, and summarizes the treatment methods of concrete cracks: surface treatment method, filling method, grouting method, structural reinforcement method, concrete replacement method, electrochemical protection method, bionic self-healing method and so on.
