Abstract
This article presents an experimental study on the thermo-physical characterization of local materials used in building construction. These materials are laterite cut blocks from three different quarries. The characterization was done with the hot plate device and the asymmetrical method was used. All the samples studied have thermal conductivities less than 0.6 W.m-1.K-1 and thermal diffusivities lower than 3*10-7 m2.s-1. These results show that the materials have good thermal performance.
Keywords: Laterite blocks, asymmetric hot plate model, thermal conductivity, thermal diffusivity, thermo-physical properties.
