Using Ceramic Waste Powder In Producing Self-Compacting Concrete, Sama Tarek Sayed Taha

Civil and Environmental Theses

Self-compacted (i.e. consolidated) concrete (SCC) is a special type of concrete that represents a great advancement towards a better quality of sustainable concrete. This unique type is known for its high flowability and superior levels of surface finish without tendency for segregation. The inherited distinct features can be achieved by the addition of high powder content as filler (i.e. size < 0. 125 mm) in the concrete mixture. The filler enhances the rheological properties of the SCC mixture without the need for using higher cement contents and hence, reduces the cost and heat of hydration. Lately, various regulating measures were imposed by governments and environmental organizations all over the world to seize the negative impact on the ecosystem resulting from huge amounts of solid waste materials being dumped in landfills causing major environmental problems. As a result, the utilization of alternative industrial waste constituents in construction materials has been the research focus for many years to evaluate their competence in SCC industry, and their feasibility as filler materials. In this study, ceramic waste powder (CWP) produced during the polishing process of ceramic tiles will be particularly investigated. Fresh and hardened tests are conducted to evaluate the influence of CWP on the rheological and mechanical properties of SCC mixtures. It was concluded that CWP can be used to successfully produce SCC mixtures with improved fresh and hardened properties. The inclusion of CWP up to 200 kg/m3 in SCC mixtures resulted in denser compacted mixtures with low permeability characteristics and high strength values. In addition to enhanced segregation resistance with good deformability and passing abilities for the mixtures under their own weight. The successful completion of …
