Self-flowing heat-resistant concrete utilizing waste electric porcelain

Abstract

The invention discloses self-flowing heat-resistant concrete utilizing waste electric porcelain. The self-flowing heat-resistant concrete contains the following components in percentage by weight: 65-70% of waste electric porcelain aggregate; 10%-15% of waste electric porcelain fine powder; 3-7% of silica powder; 12-20% of a binding agent; and 0.1-0.5 wt% of a water reducing agent is added on thebasis. The invention provides the self-flowing heat-resistant concrete for the high-temperature parts of the blast furnace foundation and the casting house platform; meanwhile, the waste electroceramics can be recycled, the content of the waste electroceramics in the obtained self-flowing heat-resistant concrete is 70wt% or above, and the use temperature can reach 1,300 DEG C or above. The high strength and good sintering stability of the waste high-voltage electric porcelain are fully utilized, secondary utilization of solid waste resources is achieved, and the cost is reduced. By adopting the zirconium-removed silica powder, impurities are few, the fluidity is good, the water consumption is greatly reduced, the material can be pumped for construction, and the construction efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to self-flowing heat-resistant concrete using waste electric porcelain. Background technique [0002] With the large-scale development of blast furnaces, the smelting strength and temperature of blast furnaces continue to increase. The foundations of blast furnaces and casthouse platforms are mostly poured with heat-resistant concrete. Traditional heat-resistant concrete is mostly combined with Portland cement. This type of heat-resistant concrete is not resistant High temperature (less than 1000°C), easy to bake and burst accidents. Use bauxite cement combined with heat-resistant concrete. The aggregates are generally tertiary bauxite or waste refractory brick aggregates. There is a large rate of change in the line of the material after burning, and the fluidity of the material is not good, so it is difficult to use pumping for efficient construction.
