A study was made of aggregates used for the production of decorative concretes. Since slabs of these concretes are planned to be used for floors and platforms that are subject to high mechanical stress, aggregates must have the necessary properties. The resistance of crushed stone to impact on a copra, abrasion in a shelf drum and frost resistance were studied. For sands used as aggregates, such characteristics as granulometric composition, particle size modulus, stability of the stabilized mixture, etc. were determined. According to the results obtained, aggregate samples were determined that are most suitable for the production of decorative concrete, which are used for the installation of decorative floors and platforms.
