C30 grade steel-doped slag recycled aggregate self compacting concrete and preparation method thereof
The invention discloses C30 grade steel-doped slag recycled aggregate self compacting concrete comprising the following raw materials by weight: 1 parts of water, 3.089 parts of natural coarse aggregate, 1.322 parts of recycled coarse aggregate, 3.822 parts of fine aggregate, 1.455-1.689 parts of cement, 0.728-0.970 parts of steel slag, 0.609 parts of fly ash, 0.064 parts of supplementary water, and 0.00495-0.0124 parts of an additive, and the water /cement ratio of the self compacting concrete is 0.33. The C30 grade steel-doped slag recycled aggregate self compacting concrete has good fluidity, filling property, and segregation resistance, the gradually loss and the strength both meet requirements related to construction, the C30 grade steel-doped slag recycled aggregate self compacting concrete is simple in preparation method, production cost of the self compacting concrete with same ratio and same strength is reduced, the steel slag and building garbage disposal problem can be solved, the pressure of resource depletion can be alleviated, and the C30 grade steel-doped slag recycled aggregate self compacting concrete is green, environmentally friendly, and suitable for industrial production.
