REUSE PLASTIC AND GLASS WASTES AS A PARTIAL REPLACEMENT OF CONCRETE COMPONENTS

The current paper investigates the possibility of replacing part of the fine aggregates, part of the cement, or both with crushed glass and plastic wastes and evaluate the change in its compressive strength. In this work, crushed glass and plastic aggregates were substituted at different percentages. The compressive strength of the developed concrete was measured after 7 and 28 days and compared with that of traditional concrete (mix ratio of 1:1.5:3). The results showed that the crushed glass wastes could be utilized in concrete as a good substitution of cement and sand. However, the results indicated that the use of plastic wastes decreases compressive strength. Such findings will significantly contribute to reducing the cost of the produced concrete by reducing the amount of used aggregates and this consequently reduces the aggregates demands/manufacturing. Less consumption of aggregates will reduce the depletion of natural resources.
