Effect of ceramic tile powder as a partial cement replacement material in mortar

Abstract

Continued construction activity is increasing demand to produce cement-based composites. Meanwhile, construction and demolition activities also generate solid waste that is disposed of in landfills. The disposal of ceramic tile waste (CTW) generated from construction projects at landfill pollutes the environment. Therefore, this study explores the impact of utilizing ceramic tile powder (CTP) as a partial cement replacement on the flowability, compressive strength and water absorption of mortar. Several mortar mixes were prepared with various percentages of CTP as a partial cement replacement in the mortar. All samples were subjected to continuous water curing. The results show that the use of an appropriate percentage of CTP results in comparable compressive strength and water absorption of the mortar. However, excessive use would result in a deterioration of mortar strength. In principle, the utilize of CTP in concrete would help to save natural resources and promote a cleaner environment.
