Abstract


Several buildings in the world are built using earth blocks. They have thermal properties that vary with the nature and the rate of their different composition. This type of  technique is most used in rural areas, which have a very cold climate in winter and a very hot climate in summer, with a significant gradient of temperature during the day. The construction using earth blocks is less expensive because it uses soil in its natural state without any loss of energy. It is easy to create walls of different dimensions in order to increase the thermal resistance of the building and to reduce the heat flow between the inside and the outside of the building. In this article, the authors will numerically study the thermal efficiency of a simple building consisting of a cylindrical chamber with side walls and a roof made using earth blocks stabilized by cement. The lower wall is confused with the ground. They will also numerically solve the heat equation in cylindrical coordinates using the finite volume method taken implicit in time using the FORTRAN program. The results obtained show that the thermal stability inside the building increases with the increase of wall thickness and the rate of cement stabilization.
