The Effect of Partial Replacement of Cement with Crushed Waste Glass in Laterized Concrete Production

Authors : G.L. Oyekan

Abstract: Technologists, engineers and scientists are continuously on the lookout for materials which can be used as substitutes for conventional materials or which possess such properties that would enable them to be used for new designs and innovations. The waste materials that can be used in making concrete are many and include both organic and inorganic wastes. These materials may be used as a binder material, as partial replacement of conventional Portland cements or directly as aggregates in their natural or processed states. This study examines the effect of crushed waste glass (CWG) when used as partial substitute for cement in laterized concrete. One mix proportion (1:2:4) of cement + CWG, sand, latente and granite coarse aggregate was used with a constant water/cement ratio of 0.65. The effect of crushed waste glass on 2 properties of laterized concrete, namely, compressive strength and workability was investigated. The results showed that the CWG did not enhance the compressive strength of laterized concrete. The compressive strength of the laterized concrete actually decreased as the percentage CWG content increased. Laterized concrete (at 25, 50 and 75% laterite content) showed an initial increase in workability with increases in percentage CWG content in the cement matrix with the maximum slump being obtained at 25% CWG content. Further increases in CWG content resulted in decreased workability. The results also showed that laterized concrete containing 50% laterite and 15% cement replacement with CWG can be used for low/medium cost housing development.
