Concrete specific heat
WebSep 1, 2024 · The specific heat refers to the amount of energy required to raise the temperature of a unit mass of a material up to a certain level (usually 1 °C). For concrete containing one type of PCM, two specific heats can be determined: specific heat of solid PCM (C pS) and specific heat of liquid PCM (C pL). WebMar 18, 2024 · Different models that simulate concrete’s specific heat are identified in Fig. 9, in which the ASCE model gives different specific heat values for concrete depending on the aggregate type. On the other hand, EC2 [ 63 ] uses one model for all types of aggregate, wherein the effect of water content is taken into account.
