Effect of sand addition on the specific heat and thermal conductivity of cement

Sand addition was found to decrease the specific heat and increase the thermal conductivity of cement, in contrast to the opposite effects of silica fume addition. The thermal conductivity increase due to sand addition was much greater when silica fume was present. The thermal conductivity decrease due to silica fume addition was much smaller when sand was present. (C) 2000 Elsevier Science Ltd. All rights reserved.
