Commercial concrete prepared from yellow river silt
The invention discloses commercial concrete prepared from yellow river silt. Every cubic meter of the concrete is prepared from the following raw materials: 250-280kg of cement, 70-100kg of coal ash, 50-70kg of superfine slag powder, 700-900kg of yellow river silt, 1000-1100kg of stone, 3-6kg of a water reducing agent and 120-150kg of water, wherein the particle size of the yellow river silt is 40-10 meshes. The strength of the commercial concrete prepared by taking the impurity-removed yellow river silt with the particle size larger than 0.4mm as a raw material and scientifically and reasonably adding other raw materials for preparing the concrete can be up to more than C40 after 28 days; in addition, the problem of easily-caused concrete cracking caused by adding coal ash can be reduced by virtue of the plasticity of the yellow river silt can be reduced; and meanwhile, due to the adoption of the formula of the commercial concrete disclosed by the invention, the consumption of cement is reduced, and the cost is reduced.
