Influence of industrial ceramic waste aggregates on elastic properties of concrete

Abstract

The deficiency of the natural resources has forced the construction sectors for the exploration of cleaner and greener materials-based concretes. The utilization of the recycled aggregates has emerged as an encouraging option to promote the sustainable production of these concretes. However, for the diverse structural applications of such green concretes their elastic traits must be assessed and designated. In this view, new type of concrete mixes were designed using the recycled ceramic waste aggregates (CWA) and their elastic properties were evaluated. The naturally occurring fine and coarse aggregates replaced with the CWA at various levels (25%, 50%, and 75%) were used to prepare the concrete mixes. The physical and mechanical properties of 54 cubical and 21 cylindrical concrete specimens were determined. The results show that aggregates replacement was found to reduce the density and enabled to accomplish the desired compressive strength of the proposed concretes. The compressive strength of the CWA concrete was equivalent to that of the control concrete. Moreover, the elastic modulus of the concretes was found to decrease with the increase in the CWA contents. It is seen that ceramic tile wastes have the potential to be used as recycled aggregate in concrete.
