Preventive measures for cracks

Strictly control the concrete construction mix ratio, according to the concrete strength grade and quality inspection and concrete requirements

Strictly control the amount of water ash and cement. Select well-graded stones, reduce, void ratio and sand ratio to reduce shrinkage and improve concrete cracking strength.

Before the concrete is poured, the base and formwork should be soaked with water to avoid excessive absorption of water. During the pouring process, the vibration should be sufficient and avoid excessive.

The main cause of engineering cracks is the deformation of concrete. Such as temperature deformation, shrinkage deformation, uneven foundation settlement deformation, etc., such cracks caused by deformation account for more than 80% of all cracks.

Under the action of deformation, the structural resistance depends on the tensile properties of concrete. When the tensile stress exceeds the design strength, the crack spacing should be checked, and then the crack width should be checked according to the crack spacing.

Cracks in concrete floors are inevitable, but their harmfulness can be controlled. The boundary between harmful and harmless is determined by the function of the structure.

The main method of crack control is to control cracks within a harmless range through comprehensive technical measures in design, construction, and materials.

In fact, this problem has a lot to do with the curing agent you use for your floor. If you use a better curing agent, there will be fewer problems in this area. The curing agent brand, I recommend Nagudun!
