| description | The invention discloses steel fiber concrete with high fracture resistance and a preparation method thereof. The steel fiber concrete comprises matrix concrete and steel fiber, and is characterized in that: the volume percent content of the steel fiber is 3.5%; and the used raw materials comprise the following materials by weight: 125-175Kg of water, 500-542Kg of cement, 25-38Kg of silica fume, 40-60Kg of fly ash, 500-662Kg of sand, 800-953Kg of stone, 10-16Kg of a pumping agent, and 250-273Kg of steel fiber. During stirring of concrete production, the steel fiber in the steel fiber concrete disclosed by the invention cannot agglomerate easily, so that the steel fiber concrete has good construction workability and can meet pouring construction requirements; the breaking strength of the concrete is greatly improved, high-performance concrete with the breaking strength of 20MPa is successfully prepared, and under an equal strength condition, the thickness of a concrete pavement is reduced, and the construction |
