<title>ABSTRACT</title>
<p>Producing "greener" concrete that meets various construction/industrial needs will have
significant positive impacts on both the construction field and the environment. This
paper investigates the use of ceramic waste powder (CWP); a waste material from the
final polishing process of ceramic tiles, in producing different concrete types;
conventional concrete (CV), self-compacting concrete (SCC), and geopolymer
concrete. The conducted study highlights the feasibility of using CWP as a cement
replacement in producing conventional concrete, as a filler and cement replacement in
making SCC, and as a main binder in developing geopolymer concrete. The study
signifies the promising opportunities of utilizing CWP as an alternative ingredient in
producing green concrete. Different concrete mixtures were prepared and tested for
various properties: slump retention for conventional concrete, flowability, passing
ability, segregation resistance and viscosity for judging fresh properties of SCC.
Strength development for all three concrete types, chloride ion permeability for
evaluating the durability characteristics of conventional and SCC, in addition to
resistivity test for the produced geopolymer. Results indicated that CWP can be used
10-30% as partial replacement of cement in CV, and 40% in SCC for producing
concrete with acceptable fresh and hardened properties. While for the geopolymer a
main conclusion was the use of alkali activating solutions with a concentration of 12M
to obtain compressive strength for structural applications.</p>
