一、前言在水电站大坝或其它大体积混凝土工程中,因水泥水化热的作用,混凝土浇筑入仓后会继续升温。在温度下降的过程中,由于内外制约,使混凝土产生龟裂。为了防止这种龟裂现象的出现,需对混凝土施工实施温度控制,在高温季节,尤其要严格控制混凝土的入仓温度和最终温升。 I. INTRODUCTION In hydropower dams or other large-volume concrete projects, due to the effect of cement hydration heat, the concrete will continue to heat up after it is put into storage. In the course of temperature drop, cracks occur in the concrete due to internal and external constraints. In order to prevent the occurrence of such cracking phenomenon, it is necessary to control the temperature of the concrete construction. In the high temperature season, in particular, the temperature and final temperature rise of the concrete must be strictly controlled.
