According to researchers, the use of secondary raw materials not only reduces costs but also reduces energy consumption. Therefore, turning old concrete into gravel requires eight times less energy than mining natural materials.
The new approach involves replacing some of the cement with an active mineral filler derived from crushed brick and concrete residue. As a small aggregate, sand from crushed concrete and broken glass is used. This composition allows you to improve the physical properties of the mixture and increase its wear resistance.
