This paper describes the stress variation in depth at 5 equidistant points of a system of 10 cement concrete slabs by finite element method taking into account heat distribution in depth. Research results will help engineers practice design and construction have a deeper insight into the nature of thermal stress acting on the plate. For each area with different temperature amplitudes, the thickness or concrete characteristics need to be designed accordingly to ensure the safety of the slab under the effect of temperature variation.
