OIL-RESISTANT COMPOSITE BUILDING MATERIAL BASED ON INORGANIC BINDER AND CROSS-LINKED POLYETHYLENE WASTE Russian patent published in 2023 - IPC C04B28/04 C04B111/20 

FIELD: building materials.

SUBSTANCE: invention can be used to create road paving elements in areas of possible oil spills, as well as to create trays and other prefabricated elements for their transportation. The composition of the oil-resistant composite building material comprises, wt.%: Portland cement grade M500 42.42-48.1, waste cross-linked polyethylene fraction 0.315-0.63 mm 18.3-24.7, polycarboxylate plasticizer 0.38-0.45, brick chips of fraction less than 0.08 mm 13.65-17.3, white soot 0.8-0.9, 10% calcium chloride solution 16-20.

EFFECT: increase in the resistance of the building material to the effects of petroleum products, an increase in its density and compressive strength, and the disposal of industrial waste.
