FIELD: chemistry.
SUBSTANCE: invention relates to composition of abrasive mixture for hydroabrasive cutting of materials. Composition includes abrasive grains from secondary technogenic wastes, having size of 10 to 630 mcm and bulk density of not less than 2000 kg/m3, and artificial or natural abrasive grains, having isometric, round shape, with size of 10 to 630 mcm and hardness of at least 7 on Moos scale.
EFFECT: result is higher efficiency of hydroabrasive cutting.
