Fired clay bricks manufactured by adding wastes as sustainable construction material – A review

• This paper consists of a review of different research, concerning bricks partially made from various waste materials.
• Clay composition was well characterized for prior researches and several types of additive have been reported on.
• Procedures for making samples have been described and compared between research and procedures followed in factories.
• Standards followed to test samples have been considered and related to those assays.
• Water absorption, compressive strength and bulk density results have been included and discussed.

This paper provides a review of research concerning the recycling of different types of wastes into eco-friendly fired clay bricks (FCB's). Materials and methods of researches are discussed. Several properties of bricks, made by incorporating additives are reviewed as well as procedures in accordance with international standards are highlighted. Most common results, grouped by type of additive, are shown and discussed. In conclusion, the reuse of waste in brick production might be an environmental friendly way to manage them. In some cases it even implies an enhancement of the bricks properties as well as an advantage for brick producers.
