Abstract
In this paper, we studied the numerical approximation of transient heat conduction equation of the brick .Brick is a natural building material used in construction, usually shaped in parallel, made of clay, sand and water, with a small amount of hay (crushed and soft straw) added to the clay block before cutting bricks to dry it under the sun. The bricks are strongly resistant and are not easily affected by weather. We applied the Finite differences method to the thermal conductivity equation for bricks. The technique is described and illustrated with a numerical example The obtained solutions are compared with the available exact solutions and the solutions obtained by Finite difference method Results showed that Finite difference method is a very promising method for obtaining approximate solutions to transient heat conduction equation of the brick. As evidenced by numerical results obtained from brick in resistance to external factors such as rain, air, sounds and others.
