Concrete for high-compressive strength section steel-concrete combined structure
The invention discloses concrete for a high-compressive strength section steel-concrete combined structure. The concrete is characterized in that each cubic meter of the concrete comprises 350-450kg of ordinary portland cement, 400-680kg of river sand, 650-950kg of gravel, 150-260kg of water, 60-80kg of fly ash, 300-500kg of heat-resistant aggregate, 20-50kg of a water-reducing agent and 20-50kg of an expanding agent, wherein the expanding agent comprises the following components in parts by weight: 10-30 parts of manganese sulfate monohydrate, 10-30 parts of alum and 10-30 parts of calcined gypsum. The concrete disclosed by the invention has the advantages of low production cost, good heat resistance, good compressive strength and good bonding strength with section steel.
