Method for enhancing concrete strength, improving volume stability and reducing cracking

The invention discloses a method for enhancing concrete strength, improving volume stability and reducing cracking. In the process of concrete forming, an upper layer slurry body is removed or drawn from an upper layer of concrete, solidity of the concrete is enhanced, hydration heat is reduced, the volume stability is improved, cracking phenomena are reduced to the greatest extent and endurance quality of the concrete is improved. According to the method, a formula of the concrete is not changed, existing concrete is used, only the upper layer slurry body is removed and the removed slurry body can be recycled and reused. The method is simple, effective, low in cost, energy-saving, environment-friendly and capable of being used for construction of the existing concrete conveniently.
