This paper investigates the potential of substituting the waste glass in making aerated light weight concrete. The physical, chemical and activity index properties of the ground waste glass are first investigated. Subsequently, the waste glass is incorporated in the aerated light weight concrete formulation as cement substitution at different ratios. The density and initial compressive strength of aerated light weight concrete result are then compared. Based on the initial experiment results, the ground waste glass can be potentially substituted up to 20% as pozzolanic material in making aerated light weight concrete.
