AbstractAbout the AuthorReferences
The negative impact of waste storage of metallurgical enterprises on the ecological situation in the city of Magnitogorsk is covered in the article. Reasons for the rare use of sand from dumped steel making slag as a fine filler for concretes which is determined by their aptitude for spontaneous destruction (decay) are considered. It is revealed that particles of size less than 0.16 mm are the most dangerous, other sand fractions are stable to the decay. The efficient use of steel making slag of 2.5–0.16 mm fractions in place of scarce river sand is proposed. It is shown that the use of open-furnace slag sand in vibro-pressed fine concretes is the most preferable due to the improvement of the adhesion strength of cement stone with the filler. This makes it possible to obtain the pavement elements with operational characteristics which are not inferior to fine vibro-pressed concrete with river sand.
