摘　　要：页岩陶粒骨料的力学、热学性能参数的合理评价是配制页岩陶粒混凝土整体性能的关键。通过细观力学的均匀质模型,结合多层次材料的力学和热学性能试验数据,反演得到通过常规试验不宜获得的轻骨料的弹性模量和导热系数。经过验证,该方法在用于预测新制备的页岩陶粒混凝土的性能中具有一定的精度。Reasonable evaluation of the mechanical and thermal properties of shale aggregate is the key to the design of the shale aggre- gate lightweight concrete.By using the homogenization model of mesomechanics, and combined the data of multi-level materials＇ mechani- cal and thermal properties, the lightweight aggregate＇s elastic modulus and thermal conductivity are deduced inversely that can＇t get easily by the conventional experiment.It is proved that the method has good accuracy in predicting the performance of the new specimens of the shale aggregate lightweight concrete.
