Raw materials for the manufacture of slag concrete can be in some cases and combine slags.
Slags to use them in case depending on the purpose exposed to a number of tests. Total tests for fuel and metallurgical slags are given in special instructions on the use of slag aggregates in concrete and reinforced concrete.
It should be noted that the general disadvantage of the huge reserves of the dual slags as raw materials for concrete is their inhomogeneity, the presence of a wide variety of slag in the growing dumps.
Considering these circumstances, as well as the reduced activity of the reducing slags, the use of them for the production of slag concrete large blocks is possible only after special enrichment.
