FIELD: technogenic dispersed soils.
SUBSTANCE: invention relates to the field of technogenic dispersed soils and can be used as technological backfills during construction earthworks. Light technogenic dispersed soil is an environmentally friendly product of utilization of sulphurous-alkaline desulfurization wastes by joint granulation with amorphous silicon oxide in the ratio of 360-440 ml of sulphurous-alkaline solution per 1000 g of dry amorphous silicon oxide, followed by firing at a temperature not lower than 700°C.
EFFECT: ensuring the production of a new dispersed soil with a low density, at the same time the properties of cohesive and non-cohesive dispersed soils - adhesion and flowability in a dry state, in the expansion of raw materials, the disposal of sulphurous-alkaline waste.
