The modulus of elasticity (MOR) of lightweight polystyrene concrete is a function of the constituent materials' proportions, namely, cement, water, polystyrene, fine and coarse aggregates. The conventional methods used to determine the mix proportions that will yield a desired modulus of elasticity are laborious, time-consuming, and expensive. The model can prescribe all the mixes that will produce the desired modulus of elasticity of concrete. It can also predict the modulus of elasticity of polystyrene lightweight concrete if the mix proportions are specified. The adequacy of the mathematical model was also tested.
