BASIC PHYSICAL AND MECHANICAL PROPERTIES OF ALKALI-ACTIVATED ALUMINOSILICATES WITH DIFFERENT CERAMIC WASTE FINENESS

Popis výsledku v původním jazyce

This article is focused on the alkali activation of aluminosilicates prepared from industrial waste obtained from the final grinding of bricks during their production. The ceramic waste powder as a precursor with water glass-sodium hydroxide mixture as activator are utilized for the production of alkali-activated aluminosilicates, which represent a promising way for design of cement-free environmentally friendly binders. Usage of such materials in building industry for development of new materials have a very good potential in this field. In this paper, ceramic waste powder with different fineness is investigated. The basic physical properties, namely matrix density, bulk density and open porosity and mechanical properties, such as compressive strength and flexural strength were studied after 28 days of curing. The porous system was examined by means of mercury intrusion porosimetry. The obtained results showed that the application of the finer ceramic waste powder led to the creation of a more compact microstructure with significantly improved compressive and flexural strength properties.
