怎样提高混凝土的抗渗、抗裂和抗侵蚀性能 ,是建筑工程大体积混凝土施工的一个关键问题。一、裂缝产生的原因1.水泥水化热引起温度应力和温度变形水泥在水化过程中产生大量的热量 ,使混凝土内部温度升高。当混凝土内部与表面的温差过大时 ,就会产生温度应力和温度变
How to improve the impermeability, cracking and corrosion resistance of concrete, is a key issue of construction of mass concrete construction. First, the causes of cracks 1. Cement hydration heat caused by temperature stress and temperature deformation of cement in the hydration process produces a lot of heat, so that the internal concrete temperature. When the temperature difference between the concrete surface and the interior is too large, it will produce temperature stress and temperature change
