METHOD FOR WINTER CONCRETING - "DRY HOT THERMOS" Russian patent published in 2001 - IPC

FIELD: arrangement of monolithic extended concrete and reinforced-concrete constructions in winter conditions. SUBSTANCE: method consists in placing of a layer of hot expanded clay aggregate at a temperature of 200 to 300 C in an installed warmth-kept formwork directly on a frozen base, it is distributed and packed in the formwork. Then, after the hot expanded clay aggregated gets cooled down to a temperature below 100 C, it is injected by cement-sand mortar. After that a temporary warmth-keeping of the concreted construction is accomplished. EFFECT: prevented power expenditures due to reuse of the heat of the cooling down expanded clay aggregate, solved ecological problem of salvaging of heat of the cooling down expanded clay aggregate. 3 dwg
