On the Composition of Sodium Silicate - Sodium Hydroxide Activator for the Waste Ceramics Recycling

Popis výsledku v původním jazyce

The building industry produces brick waste, which is not using efficiently enough. Instead of looking for the use of such waste materials, we draw on non-renewable resources, burden the environment, and all this is very expensive. This work focuses on the recycling of such waste, specifically on the ceramic powder generated in the production of brick blocks. The main aim is to assess its applicability in the field of alkali-activated materials. Several alkali-activated composite mixtures were designed and prepared. The influence of the amount of added sodium hydroxide is the independent variable under this study. The effect of varying silicate modulus on initial and final setting time, characterization of pore structure, bulk density, matrix density, open porosity, compressive strength and flexural strength was investigated. Based on the presented observation, this alternative binder sufficiently meets applicability requirements and proves comparable performance to the Portland cement. Thus, it can be concluded that waste ceramic can be used as an environmentally friendly substitution for conventional materials.
