表层混凝土导热系数对评价自然气候温度变化下表层混凝土内温度响应规律研究具有重要意义，是钢筋混凝土耐久性评价的一个重要参数。重点了解混凝土水灰比和含水率对其导热系数的影响规律；采用导热系数测定仪，对表层混凝土导热系数进行了试验研究，得到了与混凝土水灰比和含水率相关的表层混凝土导热系数预计模型。
英文摘要：
The thermal conductivity of the surface layer concrete has the important meaning in the research of the temperature response law when the natural climate temperature changes, and it is a key parameter in durable appraisal of the reinforced concrete.This article mainly studies the influence law of water-binder ratio and moisture content to its thermal conductivity;and through experimental study about thermal conductivi- ty of the surface layer concrete by using the thermal conductivity apparatus, obtains the thermal conductivity estimate model of the surface layer concrete about water-cement ratio and moisture content.
