“…Overwhelming majority of works devoted to scale processing describe granulation processes (manufacture of pellets) and briquetting, that really are preparing operations before pyrometallurgical processing [9][10][11][12][13]. Several scientific teams propose to use scale as additive to building materials [14][15][16][17][18]. Some enterprises try to solve the problem of scale processing and utilization via its use for perimeter pavement of domestic roads or as substrate / filling agent in building works; however, it is not always allowable from the point of view of ecological and industrial safety.…”

The main directions of alternative use of scale, a metal-containing waste material from forging and pressing shops at metallurgical enterprises, were suggested and researched within the framework of this work. Scale composition from the processes of heat treatment and forging of steel components from forging and pressing shops at the machine-building plant in the Moscow region was examined. It was established that up to 99 % of scale is presented by magnetic phases of iron oxides, supposedly in the form of Fe 3 O 4 , and alloying components do not practically transit in scale. The technology of sulfuric acid and hydrochloric scale processing with obtain of coagulants is suggested for purification of waste water at galvanic sections or hydrochloric pickling solutions respectively. The technology of scale use as filtrating loading for the processes of purification and neutralization of chromium-containing waste water is proposed. Hugh reducing ability of scale as a reactant for purification of acidic waste water was established in the wide range of initial concentration values of chromium (VI) compounds. Possibility of scale use as Fe-containing additive for pyrometallurgical processing of quartzite-leucoxene, a large-capacity titanium-containing mineral waste, was examined. It was established that chemically active pseudobrookite is the final conversion product; it can be used as raw material for manufacture of wide spectrum of commercial products.

This article presents the results of research that dealt with the development of non-traditional concrete using a hybrid alkali-activated cement. It is concrete based on by-products from a metallurgical plant that replaced 100% of the natural aggregates. Steel slag (CSS, fraction: 0/8 mm) was used as a filler in combination with air-cooled slag (ACBFS, fraction: 8/16 mm and 16/32 mm). Portland blended cement (CEM II/B-S 42.5N) and H-CEMENT were used as binding components in the development of the concrete mixture designs. Both of these cements were produced by Považská cementáreň, a.s., Ladce. Attention was focused on testing the physical and mechanical properties of the developed concretes in various environments. An aqueous environment was selected as the first environment for the placement of test specimens (cubes with 150 mm edges and prisms with dimensions of 100 × 100 × 400 mm3) according to the ČSN EN 206-1 standard and the outdoor environment (August to October). The determination of the cube strength was made after 7, 28, and 90 days, the determination of the flexural and compressive strength was made at the end of the prisms, and the determination of the dynamic modulus of elasticity was made after 28 days on the prisms. The test results of the test specimens, which were placed in two environments, were compared and it was found that, after 90 days, the outdoor environment caused a decrease in the concrete’s strength characteristics when using Portland blended cement (CEM II/ B-S 42.5N) of about 8%; in contrast, when using H-CEMENT, the concrete’s strength increased by about 14%. The use of H-CEMENT and the addition of PUZZOLANIT in the amount of 30% in combination with CEM II/B-S 42.5N in the amount of 70% reduced the decrease in the strength of the concrete after 90 days by about 3%. The research results confirm the suitability of using H-CEMENT and the addition of PUZZOLANIT for the production of concrete based on steel slag (CSS) and air-cooled slag (ACBFS).
