Construction technology of mass concrete The pouring amount of large volume is too large, and the overall requirements are high. During the pouring, tamping and curing process, a large amount of hydration heat is generated from cement hydration. However, due to its large volume, a large amount of hydration heat cannot be distributed. The internal temperature of the concrete is higher than the temperature of the outer concrete, resulting in a large temperature difference. Due to the different volume expansion between the surface and the inside, temperature cracks will be generated, so the hydration heat is reduced, Place the concrete inside and outside -

Discussion on construction technology of impermeable concrete [Abstract] We often come into contact with the waterproofing of buildings. In fact, waterproofing and impermeability have a lot of similarities, but different concrete is used because of the different impermeability of buildings required by the design or because buildings cannot use other additional waterproof materials. Impermeable concrete shall be used if there are specific requirements for anti permeability. And put forward prevention and treatment measures. -
