Technical Disclosure Card for Mass Concrete Pouring Project After the mass concrete is poured, the internal temperature of the concrete keeps rising due to the heat released by the cement hydration heat. The temperature difference between the concrete surface and the internal concrete is large, and the shrinkage of the surface and the internal concrete is inconsistent, resulting in great tensile stress. During this period, the early tensile strength of the concrete is very low, so the surface cracks of the concrete are very easy to appear, Therefore, effective measures should be taken to reduce -
