After concrete is poured, if the weather is hot and the air is dry, curing is not performed in time, curing moisture of the concrete in the concrete can evaporate too fast, dehydration phenomenon is formed, cement particles with gel cannot be fully hydrated, cannot be converted into stable crystals, and the cement particles lack enough cohesive force, so that flaky or powdery falling off can occur on the surface of the concrete. In addition, when the concrete has not enough strength, too early evaporation of water can generate larger shrinkage deformation and dry shrinkage cracks appear. Therefore, the early-stage curing after the concrete pouring is very important, the concrete should be cured immediately after final setting, and the dry hardness should be cured immediately after the pouring is finished.
