Minimization of Anthropogenic Impact on the Environment of Waste of Mining Complex by Recycling Them in the Soil Concrete Modified with Natural Zeolites
https://doi.org/10.18412/1816-0395-2020-6-24-29
Abstract
The article considers the possibility of reduction of anthropogenic impact on ecosystems of various levels of waste of mining complex by their largetonnage direct using in the construction industry. The methods of utilization of waste crushed production modified with natural zeolites and stabilizing additive in the composition of soil concrete are studied. The chemical and phase compositions of the inital mineral raw materials and soil concrete based on them are studied by a complex of modern methods. Optimal mass fractions of clinoptilolite rock (5–15 wt. %) and a polymeric stabilizing additive (1 wt. %) allowing to obtain composites with a maximum strength grade of 100 (М 100) are established. The increase of strength characteristics of soil concrete modified with zeolite-containing rock is associated with an increase of their density by the presence of crystalline calcium and magnesium silicates in the structure as well as the filling of the interparticle space with mineral and polymer additives.
