SPECIFIC HEAT OF SELECTED CONCRETES AND DESIGN OF REINFORCED CONCRETE FOR FATIGUE

A series of concrete mixes covering a wide range of unit weights (40-146 pcf) (640-2338 kg/cu m) 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, especially for porous 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 recommendations as to clarifications are made. /Author/
