摘要：
This paper presents a review of existing studies on the microstructure and thermal conductivity of cement-based foam. Previous studies on constituent materials, measurement techniques for thermal properties, characterization of microstructure, the thermal conductivity of cement-based foam and conductivity models for the dry porous material are included in the discussion. Based on the review, the following research areas have been identified: (i) Influence of pozzolanic admixtures and different cast densities on the thermal conductivity of cement-based foam (ii) Effect of microstructure on the thermal conductivity (iii) Governing hydrated products and their impact on the conductivity of cement-based foam.
