Since cracking in concrete is usually caused by thermal processes, relevant thermophysical properties such as heat capacity and thermal conductivity are important. This article details the measurement of thermal conductivity and heat capacity using the transient plane source method of two different (0.3 and 0.4) water-to-cement (w/c) ratio hydrated cement pastes. These thermophysical properties are measured during the initial application of the cement as well as over a period of 28 days. ...
