Annotation: The influence of the use of granite screening on the basic properties of heavy concretes has been studied. It has been established that granite screenings of the Telmanovskoye deposit meet the requirements of the current interstate standard 31424-2010, which allows the use of a material with a fraction of 0–5 mm instead of quartz sand in heavy concretes. Studies have shown that replacing quartz sand with granite screening in heavy concrete leads to a decrease in the mobility of the concrete mixture. However, it has been found that when using granite screening instead of quartz sand, the strength of concrete increases. Thus, the introduction of granite screenings in the composition of concrete in the amount of 25 % of the mass of sand leads to an increase in the strength of concrete by 8 % compared with the initial strength. The complete replacement of quartz sand with granite also does not reduce the strength characteristics of concrete. Steaming of the studied concrete samples leads to a similar increase in the strength of concrete with an appropriate content of granite screening.
Keywords: heavy concrete, granite screening, quartz sand, granulometric composition, concrete strength, steaming.
