•Reuse of waste materials in concrete mixes is a way of waste management.•Waste ceramics were finely grounded for possible evaluation in SCC as filler material.•Cement was substituted with waste ceramic powders finer than 125µm in SCC mixes.•An improvement was observed on flowability of the fresh SCC up to 15% WCP ratio.•WCPs has potential to evaluate in self-consolidating concrete mixes as filler material.
Using filler materials finer than 0.125mm is quite effective on the fresh state properties, strength and durability of self-consolidating concretes. Most common filler materials used in self-consolidating concretes are minerals, blended cements and natural or artificial pozzolans. In this study, usability of granulated waste ceramic powder as filler material in self-consolidating concretes was investigated. Properties of self-consolidating concretes produced with 550kg/m3 dosage and cement was replaced with (WCP) in the amounts of 5%, 10%, 15% and 20% (by weight) were determined in the fresh and hardened phases. As a result, it is determined that use of WCP has some positive effect on viscosity of the mixes. However, a slight decrease was observed on the strength values based on the substitution of cement with ceramic powder. It can be concluded that finely ground WCPs could be evaluated up to 15% for production of self-consolidating concretes as a filler material if the strength and flowability parameters are evaluated together.
