Sustainable Construction with Plasticized Clay Bricks in Concrete: Review

Abstract

The application of plastic fibres and clay brick wastes collected from dumped sites is a great issue in every country, owing to their inconsistency in the wastes streams. This review aims to analyze current and future trends of research on the use of plastic fibres and clay brick waste with the aim of substituting both for natural coarse aggregate (NCA) in normal concrete. The various findings of this study would be applied in
construction of lightweight concrete thus economizing construction cost, hence helps in conservation of natural resources. Plastics waste,
are generated from discarded water bottles, polythenes - any synthetic materials that has reached its end of life while waste clay bricks are found from broken partition clay blocks or clay hollow pots. Tests results of previous work done by various researchers are presented in order to give an overview of combined effect of both plastic and clay bricks aggregate in concrete. Hardened properties of the concrete such as hard density as well as the compressive and flexural strengths determined. The percentage substitutions that gave higher compressive strengths would be used to determine performance of the combined effect. The findings of this investigation revealed that the mixture of plastic fibres and clay brick waste materials could be used successfully as substitutes of NCA for lightweight concrete.
