Research On The Repairing Technology And Materials For Concrete Cracks

With its high compressive strength of concrete materials,fire resistance,and the use of flexible,convenient construction to become the world's most widely used,the amount of one of the largest construction materials,other materials are playing an irreplaceable role and function. However,the brittleness of concrete materials,easy corrosion,in the course of their service may be subject to internal factors and the role of the external environment,resulting in cracks,corrosion and other localized injury and disease,over time,the disease will gradually increase,A result,the performance of concrete materials continue to lower the light will affect the structure of the normal use or shorten the life of the structure,weight will have catastrophic accidents,to the national economy and people's lives and bring great loss of security. Although cracks in the concrete is almost inevitable,but most were able to pass through cracks in concrete structures repaired to restore the original function. In order to improve the durability of concrete structures,reinforced concrete structure using function,you can appear on the structural components of the repair concrete cracks. It can be said that the repair of concrete cracks have great theoretical value and practice. Repair cracks in concrete from the repair,there are two ways in theory,one after the repair of concrete cracks,ranging from the aesthetic point of view the building or the use of anti-leakage and other special considerations for the repair of concrete cracks and to consider the structural safety of durable reinforcement of the structure considered; Another component is the structure of their own self-healing of cracks. This paper studies include concrete crack repair techniques and treatment methods,performance analysis and binder selection,and performance verification of the binder.
