SULFUR CONCRETE PRODUCT IN THE FORM OF PILES, SUPPORTS OR FOUNDATION BEAM AND METHOD FOR ITS MANUFACTURE Russian patent published in 2023 - IPC E02D5/22 

FIELD: construction.

SUBSTANCE: manufacture of construction products and structures made of sulfur concrete. Method for manufacturing a sulfur concrete product in the form of a pile, support or foundation beam includes laying a reinforcing cage into the formwork and filling the formwork with a sulfur concrete mixture at a temperature of 140-150°C with gradual cooling to the outside temperature. The formwork is made with the possibility of directional control of the temperature deformation of the solidifying sulfur concrete mixture, free in the transverse direction and hindered in the longitudinal direction. Casting shrinkage is regulated by creating longitudinal obstacles - shrinkage regulators along the length of the working reinforcement, for which at least two opposite sides of the formwork are made with alternating protrusions of the sides of the formwork transverse relative to their longitudinal axes, which do not create a reduction in the section of the product, or with alternating bevels of the sides formwork with a length of 1-3 B, where B is the size of the side of the product section.

EFFECT: providing directed regulation of shrinkage deformations.
