Abstract

Eco-materials are becoming the one of the important matters to be addressed in industries and academics owing to reduce the impact of synthetic materials on environment. On the other hand, waste materials have becoming an equal important matter in term of disposal and their impact on environment. In civil engineering, exploring any potential eco-materials for structural components is the ambition of many engineering and environmental researchers.

In this project, an attempt is made to explore the potential of using waste ceramic particles in concrete. The structure and the compressive characteristics of the developed materials with different waste ceramic particle percent are investigated. Different concrete samples were prepared and tested. The failure mechanisms were determined after the completion of the experiments. The optimum percent of waste ceramic particles in concreate were determined from workability, compressive strength and structure of the concrete. Compressive strength of the developed concretes were tested at different curing duration of 7, 14 and 28 days. Visual examination and scanning electron microscope were used to observe the failure mechanism.

The experimental results were in high agreement with the published recent and related works. The content of the waste ceramic particle controlled all the characteristics of the ceramics, i.e. workability, compressive strength, and the structure. Increase in the content of the waste ceramic particles deteriorate the strength of the concrete especially at content of above 25 wt. %. Despite of that the reduction in the strength at low percent of waste ceramic particle were within the industrial recommended ranges. Also, from environmental point of view, a promising results are identified and 25 wt % of waste ceramic particles in concrete is highly recommend. The failure of the concreate was commonly due to the crack generation and/or propagation in the bonding region of the particles and the cement. At high percent of waste ceramic particles, there is micro- and mac-cracks propagated which resulted in the poor performance of the concreate at this high percent of particle.
