预冷混凝土在干热地区核电站工程中的应用

Application of precooled concrete for the construction of a nuclear power plant in dry and hot region

本文介绍了预冷混凝土在干热地区电站工程中的应用，提出了控制混凝土搅拌站的出机温度、原材料冷却、冷冻水和冰片的掺加等一系列方案，并详细介绍了这些方案在工程中的具体应用情况，对干热地区大体积混凝土降低温度提供了经验。

In this article, an application of precooled concrete for the construction of a nuclear power plant in dry and hot region is introduced. Besides, it has put forward a series of technological measures namely (1) the control of concrete's temperature at the concrete mixer's outlet, (2) the cooling down of concrete's raw materials and (3) the using of icecold water and icide as concrete's admixtures etc. In addition. it has shown in detail about these measures for practical application. As a result, it would be a good experience and beneficial reference for the cooling down construction of a mass concrete structure in dry and hot region.
