Title: Specific Heat of Selected Concretes

Abstract:A series of concrete mixes covering a wide range of unit width (40 - 146 pcf) (640 - 2338 kg/m3) were prepared. Specific heats were experimentally determined using a method of mixtures technique and calculated for the entire range of moisture content using a rule-of-mixtures approach. Results indicate that moisture content exerts a strong influence on specific heat, espically for porus lightweight mixes. The relationship between moisture content and specific heat is almost linear for normal weight and structural lightweight aggregate concretes, but deviates from linearity for the lower density mixes studied. Results are compared with ASHRAE handbook values and reccomendations as to clarifications are made.
