概要

論文の詳細を見る
It is briefly reviewed and commented that recent studies on effective thermal conductivity of the three phased material. The author also explains a new three phased model on the effective thermal conductivity of porous material derived by the authors recently from experimental values for eighteen kinds of porous rocks at dried, moist and water saturated conditions. Accuracy of the model is shown for the eighteen kinds of rocks within ±22%, for one hundred twenty-eight alteration core samples ±20%, for normal concrete ±10%, for short fiber reinforced concrete ±15% and for light weight concrete ±10% except for two data for the concrete having very large porosity.
