COMPOSITE BUILDING MATERIAL Russian patent published in 2014 - IPC C04B28/04 B09B3/00 C04B111/20 

FIELD: chemistry.

SUBSTANCE: claimed invention relates to composition of composite building material. Composite building material contains drilling waste, cement in quantity from 10 to 20% of drilling waste volume, technical carbon from 0.5 to 1% of drilling waste volume, quick lime in quantity from 3 to 5% of drilling waste volume, peat in quantity form 5 to 10% of drilling waste volume, sand in quantity from 10 to 30% of drilling waste volume, and building material in addition can contain hydrocarbon-based drilling fluid used or unused with content of hydrocarbons in quantity from 10 to 50% of drilling waste volume.

EFFECT: increased degree of environment protection, obtaining ecologically safe building material with increased durability and resistance against wind and water erosion, binding in structure polluting substances, excluding their migration into environment and strengthening slopes of highways, sand bankings of technological areas, for instance, from erosion during downpours and floods, strengthening construction sites, including those with non-homogeneous, and unstable composition of ground.
