ABSTRACT |
Clays are complex materials of practical and academic interest because of their variety of applications in construction industries and Engineering fields. A study of the properties of clay samples from different locations in Ondo town has been performed. Determination of thermal conductivity, resistivity and sedimentation were carried out in the Laboratory using simple Lee’s Disc apparatus and laws of floatation. Four different clay samples from different locations were analyzed. Results of analyzes revealed that the samples textures were more of silt and clay and are yellowish in colour. The results further showed that the clay samples have different thermal conductivities and rates of cooling. The salt content of the samples in Ondo was observed to be very minimal, so therefore, small quantity of current will flow through the building constructed with such clay samples analyzed. This study showed that gray clay sample has the highest thermal conductivity and emissive power while white clay sample has the lowest thermal conductivity and emissive power. Implications of the general characteristics of the clay samples on their potentials as a location building material were subsequently discussed.
