摘　　要：高大部位混凝土施工过程中,需要对混凝土的阶段强度进行了解。文章通过在高大部位混凝土中预埋的温度传感器,将混凝土内部的温度传给数据采集器,并引入混凝土成熟度指标,建立了混凝土温度-强度关系曲线。当混凝土温度及时间数据达到成熟度指标的对应值时,即认为高大部位混凝土强度达到预测强度。It is necessary to understand the stage strength of concrete during the construction of high and large concrete.The article pre-embed the temperature sensor in the concrete of the tall part,which transmits the temperature inside the concrete to the data collector,and introduces the concrete maturity index to establish the concrete temperature-strength relationship curve,and the concrete temperature and time data reach maturity.When the index corresponds to the value,it is considered that the concrete strength of the tall part has reached the predicted strength.

关 键 词：高大部位 混凝土成熟度 预测强度
