Utilization of ceramic waste as partially cement substitute – A review

Abstract

Extreme demand for natural resources, particularly for cement ingredients, was drifted by the noticeable growth in the construction industry. Furthermore, cement production has an adverse impact on climate change, because of the tremendous amount of emission of CO2 from this process. On the other hand, ceramic production leaves behind considerable amounts of by-product waste as well as there is a huge amount of demolition ceramic products every year which are investigated by many researchers to partially replace cement and shrink the danger if the mentioned issues. This research reviews the previous investigations of cement replacement with ceramic waste powder (CWP) regarding the fresh, mechanical and durability properties of mixes including cement paste, mortar, concrete and SCC. The conclusions suggest that, through cement substitutions, the majority of properties in fresh and hardened mixtures, in particular, their workability and compressive strength are degraded with CWPby an additional 20%. The durability properties including acid resistance, chloride ion ingress, rapid chloride permeability, electrical resistivity, corrosion and water absorption are nevertheless somewhat improved. Overall, the beneficial effect appears only atup to 20% substitution. The microstructure tests indicate a denser structure of concrete after adding CWP. Also, more non-evaporable water is observed via the TGA test. This paper contains recommendations and observations for future research.
