Classical adiabatic methods for measuring specific heat in a wide temperature ange are very suitable for homogeneous, well defined materials. However, measurements on inhomogeneous materials require large samples, which makes using of adiabatic treatments extremely expensive. In this paper, a nonadiabatic method for determining the specific heat of inhomogeneous building materials within the wide temperature ange of-30 to 1200 ~ is presented. The method is rela-tively simple, very cheap, and sufficiently accurate for use with building materials. Tests of the new developed method on two typical building materials, concrete and basalt fibreboards, de-monstrate the method's applicability to practical measurements
