Self-compacting pumped concrete
The invention discloses self-compacting pumped concrete. The concrete comprises the following components: 365-375 kg/m<3> of Portland cement, 750-790 kg/m<3> of sand, 880-910 kg/m<3> of stone, 6.24 kg/m<3> of an efficient water reducing agent, 90-110 kg/m<3> of fly ash, 40-60 kg/m<3> of mineral powder and 150-160 kg/m<3> of water. The formula of the concrete provided by the invention is obtained through multiple proportion tests, and the appropriate efficient water reducing agent is added in the formula as an additive, so that the coagulation time of the concrete is prolonged under the condition that the property of the concrete is not influenced, and pulp and auxiliary materials are relatively good in wrapping property.
