FIELD: devising of technogenic rocks or materials based on sludge after treatment of household and industrial sewage. SUBSTANCE: invention is based on use of synthesis of organomineral binding compositions in combination of sludge with specially selected ingredients. This provides for cementation of sludge without its preliminary dewatering, that promotes economy of energy resources and labor input. EFFECT: provision of conversion of sludge into technogenic rock characterized by ecological safety and high economic efficiency due to utilization of additional ingredients in the form of solid industrial wastes and extremely low amounts of alkali reagents of the lime type, cement, etc; no need in large consumption of energy resources, for instance, for dewatering of sludge and use of expensive equipment (band vacuum filters, etc). |
