Abstract
This article addresses the development of a translucent and air purifying concrete containing waste glass. The concrete composition was optimized applying the modified Andreasen & Andersen model to obtain a densely packed system of granular ingredients. Both untreated (unwashed) and washed waste glass fractions were utilized in concrete. The fresh and hardened concrete properties were investigated. In order to ensure a durable material, the expansion due to the alkali-silica reaction was also analyzed. Subsequently, concrete tiles of different thicknesses were produced and their translucency was quanti- fied. Additionally, two different types of TiO2 were utilized in concrete to analyze the glass aggregates effect on the photocatalytic degradation of air pollutants (NO and NO2). The obtained results indicate that the developed concrete has satisfactory mechanical properties, coupled with good durability, translucency and enhanced air purification properties.
