COMPOUND FOR BUILDING BASE OF MOTOR ROAD Russian patent published in 1997 - IPC

FIELD: motor road construction technology. SUBSTANCE: this relates to road building materials which ensure high and uniform stability of motor road pavement in process of operation and prolongs service life of motor road. Compound quickly acquires required strength during first month of hardening and continues to get strength in time. Use of compound cuts cost for transportation of ferrochromium slag. Compound has following components: self-decomposing slag based on two calcium silicate, granulated blast-furnace slag, non-organic additive, water, and earth as filler. Used as self-decomposing slag based on two calcium silicate is slag mixture produced in result of benefication of slag melt with calcium-bearing substances, or open-hearth slag. When used as non-organic additive it contains magnum chloride or aluminium chloride or ferrum chloride or potassium chloride or sodium chloride or calcium chloride or ammonium chloride or their mixtures at following relation of components, mas.%: self-decomposing slag based on two calcium silicate, 15-25; granulated blast-furnace slag, 0.5-15; chloride, 0.3-2; water, 4-8; earth, the balance. EFFECT: high efficiency. 2 tbl
