Використання тонкодисперсного склопорошку як часткова заміна цементу та вплив його на міцнісні характеристики бетону

Concrete is the most commonly used commercially produced building material and its popularity is increasing rapidly daily [1–3]. The main components used in the production of concrete are cement, coarse and fine aggregates, water and additives [4–6]. These materials are essential for the construction industry [7–10]. Active mineral additives (AMAs), such as ground granulated blast furnace slag, fly ash, silica fume, etc., are used to improve various properties of concrete mixes. The amount of glass waste generated has gradually increased in recent years. Most glass waste has a limited lifespan and ends up in landfills, but it should be reused to reduce environmental problems as it is non-biodegradable [11–13]. Recycling and waste reduction are critical aspects of waste management systems, as they help preserve natural resources, reduce landfill space requirements, and reduce water and air pollution [14]. Extensive research is currently being carried out to modify and improve the properties of concrete by adding various types of materials, in particular glass powder, due to its pozzolanic activity and suitability as an AMA. This paper presents the optimal use of waste glass in concrete mixes to improve concrete quality. Glass powder with a particle size of less than 100 microns was used in this study. The study included different percentage concentrations ranging from 0 to 15 %. A series of tests were carried out to investigate the effect of glass powder on concrete strength.
