Effect of Temperature on Strawbale Wall Rendered with Laterite and Clay Nanoparticle

Abstract

In this study, the influence of the plastering materials on the thermal performance of three (3) straw bale building models were evaluated. The plastering materials considered are laterite mortal, laterite mortal with nanoparticle clay screeding and cement-sand mortal. The results were based on the experimentally measured thermal conductance, thermal resistance and thermal transmittance of the building model according to ASTM C1045-90 standard specification. The analysis of the measured data revealed that the laterite plaster significantly improve the thermal resistivity of the building model compared to cementsand mortal. However, clay nano particle screeding on the laterite plaster does not significantly affect the thermal performance of the straw bale building model.
