Abstract: Specific heat is the amount of heat that a unit mass of a material must gain or lose to change its temperature by a given amount. The specific heat of a material is associated with the heat capacity, except the specific heat doesn’t depend on an object’s mass, though it depends on the types of material. Specific heat measures the index of the facility with which concrete can undergo temperature changes. Specific heat is also related to thermal conductivity and thermal diffusivity. For this reason measurement of specific heat of concrete is very essential. The aim of this study is to build up an arrangement for measuring specific heat of normal strength concrete and the comparison of the specific heat with different types of concrete and also to observe the variation of current and voltage with respect to time. Unit weight, Voids, Moisture content and Specific Gravity was measured for measuring specific heat by using bricks khoa and stone chips as coarse aggregate and the samples are covered with and without glass wool. The specific heat of concrete varies with the mixing ratios of ingredients of concrete. The specific heat of concrete with denser mixing ratio is greater than concrete having looser mixing ratios.
