– Sergey, what kind of road construction are you talking about?
– We believe that it is possible to significantly change the ecological situation and simultaneously develop the road network, if we use the advantages of concrete roads made with composite binders based on technogenic raw materials, which are the metallurgical, chemical and energy plants' waste.
– Let's start with the fact that the area occupied by waste amounts to hundreds of thousands of hectares. The annual volume of emitted industrial waste is comparable to the annual volume of cement production in Russia. For example, now fly ash, or pulverized fuel ash, is barely utilized, it pollutes the Thermal power plant's surrounding area. One TTP produces about 150 thousand tons of ash per year. Imagine what the volume is across the country.The cement industry can use these by-products to create road building materials. The fundamental difference is that producing road pavement materials we refuse to use non-renewable natural resources, and instead use existing soils simply strengthening them with composite binders using industrial waste. This way we obtain high-quality slag-alkali and geopolymer concretes, which are excellent for paving roads.
