摘要：大体积混凝土温度控制的关键在于降低混凝土水化热以及减小混凝土内、外温差，避免产生过大的温度应力，使得混凝土在前期强度较低的情况下不至于受到过大的拉应力而产生裂缝。控制混凝土内、外温差的主要措施有：降低混凝土入仓温度、降低混凝土水化热、混凝土外部保温以及混凝土内部降温。 关键词：大体积 ； 混凝土 ； 温度控制医用拉链 ； 措施
Abstract: the key of big volume concrete temperature control is to reduce the hydration heat of concrete and reduce concrete internal, external temperature, avoid excessive temperature stress, which in the early strength of concrete under the condition of low not have been too big tensile stress cracks. The main measures to control the concrete temperature, are : to reduce the temperature of concrete pouring, reduce the hydration heat of concrete, concrete external thermal insulation and internal concrete temperature.
