In this work, an experimental study is conducted to compare the properties of aggregate from concrete waste generated during demolition, concrete laboratory waste and natural aggregates – which are used as control samples. The study examines the possibility of using demolition waste to develop building materials with stable properties, in order to obtain economic benefits from the disposal of man-made waste. Initially, the production of aggregates from waste is carried out by crushing concrete scrap from demolition waste and laboratory waste, followed by the study of their physical and chemical properties to obtain aggregates and concrete mixtures, the production of samples, and the determination of compressive, flexural and tensile strength. The correlation between the results obtained from various experiments is analyzed and a linear correlation between the compressive strength and other established mechanical properties is noted. The possibility of recycling construction waste, leading to the solution of several problems, is presented: reducing the cost of industrial waste disposal and improving the physical and mechanical properties of concrete by introducing it as a filler.
