COMPOSITE RAW MIX FOR THE PRODUCTION OF FIBER-REINFORCED CONCRETE Russian patent published in 2022 - IPC C04B28/04 C04B14/02 C04B24/00 C04B111/20

Abstract RU 2770375 C1

FIELD: construction.

SUBSTANCE: invention relates to building materials and can be used in road construction. Composite raw mix for the manufacture of fiber-reinforced concrete contains Portland cement, quartz sand, wire steel fiber and water, and the raw mix contains Portland cement grade CEM 1 52.5 N, quartz sand with fineness modulus М_fn=2.65, as a wire steel fiber, Hendix fiber is used in the form of a straight segment with a nominal length of 50 mm with anchors in the form of limbs at both ends, and additionally the raw mix contains the additive Linamix PK, in the following ratio of components, wt.%: specified Portland cement 20.59-22.5; specified quartz sand 61.5-65; additive "Linamix PC" 3-5; fiber "Hendix Hendix" 1.1-3; water 8:31-11.

EFFECT: invention improves the strength characteristics (R_izg; R_szh) of crack resistance (K_c*), frost resistance (F) and water resistance (W).
