Abstract


Crack is a fairly common phenomenon in the construction of concrete structures , long plagued with technical problems in the construction engineering and technical personnel . Practice has proved that the crack is unavoidable, but it can be controlled in the sound within the range . This paper analyzes and summarizes the mechanism of shrinkage cracks and mass concrete hydration heat temperature common in the construction of concrete structures , concrete floor cracks , shrinkage cracks , mainly due to the loss of water drying shrinkage , the temperature of the heat of hydration of mass concrete cracks the main reason is the gradient and temperature rate of change of the temperature difference between inside and outside of the concrete , second hand pressure to prevent shrinkage cracks and insulation moisture to prevent the temperature of the heat of hydration of mass concrete cracks with covering moisture conservation in engineering applications have made certain success.
