Effects of silica fume, latex, methylcellulose, and carbon fibers on the thermal conductivity and specific heat of cement paste
Due to their poor conductivity, latex (20 % to 30 % by weight of cement), methylcellulose (0.4 % to 0.8 % by weight of cement), and silica fume (15 % by weight of cement) decreased the thermal conductivity of cement paste by up to 46 %. In addition, these admixtures increased the specific heat of cement paste by up to 10 %. The thermal conductivity decreased and the specific heat increased with increasing latex or methylcellulose content. Short carbon fibers (0.5 % by weight to 1.0 % by weight of cement) either did not change or decreased the thermal conductivity of cement paste, such that the thermal conductivity decreased with increasing fiber content due to the increase in air void content. The fibers increased the specific heat due to the contribution of the fiber-matrix interface to vibration.
