Shrinkage Cracks In Concrete Structures Of Mechanism Analysis And Control

The micro-cracks in concrete is due to the composition of the concrete physical and mechanical properties of materials inconsistent,hardened cement paste after the shrinkage of greater value,the concrete in the aggregate they are restricted in cement paste free of contraction,such constraints, such as the role of the concrete after the in-house video from the beginning in the aggregate and cement paste bonded on the surface of the micro-cracks appear. In other words, even in the absence of external loads,or even changes in the volume of concrete occurred when the load is no external constraints,concrete has an internal micro-cracks,When the external force or deformation of a larger role, these micro-cracks in the surface of the bond will be development.Therefore, macro-micro-cracks are cracks in the foundation, we have to start up the source of control, in order to better control the cracks in the concrete. this article from the control of materials, structural design, construction control in three areas, micro-cracks in the concrete on the prevention and treatment elaborate. Application and analysis, relevant content available.
