Abstract:

The basis of construction is made of materials such as: wood, stone (including
artificial stone, i.e. concrete and brick), steel and glass. Currently, the glass is a product that
enjoys increased interest, also due to the phenomenon of recycling. At the moment,
construction industry is a field in which good solutions are sought for the proper management
of waste. One of the recycled waste is glass cullet coming from bottles mainly of wine. Not
every country produces wines because there are no suitable conditions, but wine is drunk in
every country. Powdered glass is already applied in the form of glass powder in concretes
(research conducted in India, China and America), and the results of the research are the basis
for exploring this topic in the context of other materials. The paper presents the results of
research on modifications of sand-lime materials using cullet (glass sand). Non-destructive
testing of samples was carried out: lime hydration control in a mixture containing powdered
recycled glass, /humidity that affects the water absorption of the product, and further on
density and strength (water migration in the pores) and microstructural investigations. The
conducted tests showed increased humidity of the modified product with recycling glass
(approximately 2% compared to the reference sample of 0.5%) and the presence of hydrated
calcium silicates in the form of gyrolite as a phase resulting from high pressure.
