针对混凝土工程中普遍存在的裂缝问题，混凝土的裂缝不仅会影响工程质量的整

For cracks in concrete engineering ubiquitous concrete cracks will not only affect the quality of the project overall appearance of the image, but also reduce permeability and freezing capabilities, and can cause steel corrosion, affect the durability of structures, the impact of structures function of normal use, further expansion of cracks may even lead to collapse. Therefore, the analysis of the causes and hazards of concrete crack formation were analyzed and discussed, and put forward concrete measures for the prevention and treatment of cracks from raw materials, alkali content, reinforcement, pouring, curing and other proposed concrete cracks prevention measures, better prevention and treatment of the cracks, to ensure project quality.

In view of the common cracks in concrete engineering, the cracks of concrete will not only affect the overall appearance of the project quality, but also reduce the ability of impermeable and antifreeze, and will lead to corrosion of steel bars, affect the durability of structures, affect the normal use of structural functions, cracks may be further expanded or even lead to collapse accidents. Therefore, the reasons and hazards of the formation of concrete cracks are analyzed and discussed, and the prevention and control measures of concrete cracks are put forward from the aspects of raw materials, alkali content, banding, pouring, maintenance, etc., and the prevention and control measures of concrete cracks are put forward, so that the cracks can be better prevented and controlled and the quality of the project is guaranteed.

In view of the common crack problems in concrete engineering, the crack of concrete will not only affect the overall appearance of the project quality, but also reduce the impermeability and frost resistance, and lead to steel corrosion, affect the durability of the structure, affect the normal use function of the structure, and further expansion of the crack may even lead to collapse accident. Therefore, the causes and hazards of concrete cracks are analyzed and discussed, and the prevention and control measures of concrete cracks are put forward from the aspects of raw materials, alkali content, reinforcement, pouring, maintenance, etc., and the prevention and control measures of concrete cracks are put forward, which can better prevent cracks and ensure the project quality.<br>
