The usage of lightweight materials in construction has become increasingly popular due to huge available of such materials either artificially made or from industrial and organic waste.
Among the lightweight materials that have been used as materials in construction are extruded polystyrene, foamed concrete, lightweight aggregate, plastic bottle, aluminium, and even products from plantation such as peanut shells and rice husk.
Studies have proven that certain materials mentioned above are viable to be used as building materials.
The proportion for the materials used to cast the concrete beam is presented in Table I.
The proportion of these materials were measured by weight.
