- Abstract:
-
Generally, the amount of cement used in commercial concrete is relatively large, and the hydration heat generated is more, and in large-volume pouring or winter construction, it is easy to cause excessive temperature difference between the inside and outside of concrete, thereby causing cracks, so in the design, the joints, stress concentrations and large volume of concrete in the structure should be evenly arranged along the section of fine and dense structural steel bars to improve the crack resistance of the structure. By adding various admixtures to commercial concrete, appropriately reducing the amount of cement, extending the curing time, and reducing the temperature difference between the inside and outside of the component, the possibility of cracks in the concrete structure is reduced.
