Scientific novelty
The development relates to the production of new building materials, specifically the use of waste as concrete fillers. The proposed solution allows for the efficient disposal of high-volume waste, such as sewage sludge incineration ash. The product of the development — lightweight ash concrete — has potential for implementation in urban environments and can be used for the production of wall blocks and urban landscaping elements. At the same time, concrete based on incineration ash is characterized by high strength indicators. The raw mix for ash concrete production is more technologically advanced than known analogs, as using ash as a binder does not require additional component processing or additives.
Advantages
The compliance of sewage sludge incineration ash with the requirements for lightweight concrete components has been established; The preservation of concrete strength properties when adding ash to the raw mix as a partial cement replacement has been confirmed; An assessment of the environmental and economic efficiency of the development showed that using incineration ash for the production of building materials solves the following tasks: beneficial waste recycling (over 16 tons/year for SUE "Vodokanal of St. Petersburg"); freeing up landfill space and reducing negative environmental impact; obtaining lightweight ash concrete promising for use in construction, road repair, and urban landscaping.
Commercial implementation
The primary region for the development's implementation is Saint Petersburg. Currently, the sewage sludge incineration technology used by SUE "Vodokanal of St. Petersburg" is unique in the Russian Federation. The proposed concept of beneficial waste utilization allows for expanding the scope of application to include any thermally treated waste, which is relevant for all regions of Russia as well as abroad. The ash-based building material can be sold to developers and road construction companies for the production of asphalt concrete, wall blocks, etc.
