The study on the possibility of heavy-weight concrete production using diopside aggregates from Aldanslyuda ore mining and processing plant has been conducted. It is established that diopside crushed stone, namely, the crushed stone mixture of fractions from 5 to 20 mm is suitable for concretes of strength class up to 60 MPa production. It is recommended to carry out further validating research on the application of diopside rocks in high-strength concrete production. To do that it is necessary to use river sand, the water demand of which is less than of the sand from sifting of crushing solid stone, as a fine aggregate or to replace part of the latter. The physical and mechanical properties of the concretes developed on the basis of diopside aggregates have been investigated.
