Mechanical properties of concrete utilising waste ceramic as coarse aggregate

• Coarse aggregate replacement scheme in standard strength structural concrete.
• Minimal effect on mechanical properties at replacement ratios as high as 100%.
• Variety of ceramic tile materials tested showing viable real world application.

The importance of sustainability and recycling has become increasingly recognised and understood in academia and industry over the last several decades. Recycling construction and debris waste is one of many avenues that provide a great opportunity to prevent waste material from entering landfills and reduce the construction industry reliance on decreasing natural resource supplies. A coarse aggregate replacement scheme in concrete is investigated with three different waste ceramic tile materials in replacement ratios including 20%, 25%, 35%, 50%, 65%, 75%, 80% and 100%. Results show waste ceramic as a possible practicable natural coarse aggregate replacement material with minimal changes in mechanical properties.
