Analysis of Thermal and Electrical Properties of Laterite, Clay and Sand Samples and Their Effects on Inhabited Buildings in Ota, Ogun State, Nigeria

Buildings are faced with situations bothering on effects of heat and electric current flow on occupants. Thermal comfort as well as the quantity of current expected in buildings is of paramount importance. Core materials used in erecting buildings were considered during this study. This study is meant to analyze the thermal and electrical properties of laterite, clay and sand samples thereby picking out the most suitable for inhabited buildings. The results obtained revealed that the samples considered have different thermal conductivities, electrical resistivity and rates of cooling. Based on the thermal and electrical properties of laterites obtained, it is therefore imperative to establish the need to embrace it as local building material while sand and clay could be used in the production of pipes, roof tiles and interior floor where the heat conductivity is of secondary concern. Laterite based buildings using NBRRI interlocking should be encouraged more in Nigeria especially those living in hot regions.
