Beschreibung
Zusammenfassung:	The invention provides pump concrete doped with low-quality recycled micropowder and low-quality recycled aggregate, and belongs to the field of building materials. The pump concrete is composed of the following raw materials including cement, the low-quality recycled micropowder, slag powder, fly ash, mixed fine aggregate, mixed coarse aggregate, a compound pumping agent and water, wherein the mixed fine aggregate is composed of low-quality recycled fine aggregate and common fine aggregate; the mixed coarse aggregate is composed of low-quality recycled coarse aggregate and common coarse aggregate; and the compound pumping agent comprises a salt of sulfonated polystyrene-acrylic acid copolymer and a salt. The pump concrete has the characteristics of good work performance and excellent mechanical properties and durability, and can be pumped easily.
