WebThe specific heat of normal weight concrete is not very much affected by the type of aggregate, temperature and other parameters. Typically the values of specific heat are in the range of 0.22 to 0.25 Btu/lb.F. Thermal conductivity gives the flux transmitted through a unit area of a material under a unit temperature gradient. WebThis is expressed mathematically as: q = m⋅ c ⋅ ΔT, where. q - the amount of heat supplied; m - the mass of the substance; c - the respective substance's specific heat; ΔT - the change in temperature. So, if we want to determine the units for specific heat, we'll just isolate the term in the above formula to get. c = q m⋅ ΔT.
