Abstract
The use of expanded polystyrene (EPS) beads in fully or partially replacing the normal aggregate is prevalent in the construction industry nowadays. The present study covers the use of EPS concrete layer to replace the bottom concrete cover of normal reinforced concrete slab. The aim of this project is to study the flexural strength and thermal conductivity of the composite layered slab of EPS concrete and normal concrete. The EPS concrete is prepared by 50% replacing the coarse aggregate and 50% replacing the fine aggregate by volume with EPS beads. Two loading patterns are applied on the specimen: shear dominant loadings and bending dominant loadings. The flexural strengths of the composite layered slab for specimen subjected to shear dominant (SDEC) and specimen subjected to bending dominant (BDEC) is reduced 5.60% and 25.66% respectively as compared to the normal reinforced concrete slab. The results show that the replacement of EPS concrete with the normal concrete cover performs well under the shear dominant but reduce when subject to bending dominant. The thermal conductivity for composite layered specimen shows the temperature increment less than the normal concrete specimen. The EPS concrete layer acts as the bottom cover has decrease 5.00% from point at 75mm to 25mm from top. The closed air-filled cell structure of EPS beads inhibits the passage of heat and provides better thermal insulation. The composite layered slab of EPS concrete and normal concrete is recommended to utilize as roof slab.
