METHOD FOR PROCESSING DRILLING WASTES Russian patent published in 2017 - IPC B09B3/00 

FIELD: construction.

SUBSTANCE: method involves introduction cement and sorbent into wastes, hardening of the semi-finished product to produce finished construction material. Wastes are mixed with 10–20 % of natural sand and 0.6–1.0 % of Unisorb-Bio sorbent of the weight of processed wastes. Obtained mixture is dehydrated to moisture content of not more than 30 %, oil-well portland cement 1–50 is added in an amount of 20–30 % of the weight of the dehydrated mixture, also added is the hardening accelerator in an amount of 0.8–1.0 % of weight of oil-well portland cement, produced mass is briquetted at pressing pressure from 30 to 50 MPa, obtained briquettes are hardened to the required strength of a finished construction material.

EFFECT: use of the invention allows to produce strong construction molded material.
