Get beautiful photos on every new browser tab } 100% } 100% } The workability of pumped concrete in general have a average slump of between 50 mm and 100 mm. A concrete of less than 50 mm slumps are impractical for pumping, and slump above 125 mm should be avoided. In mixtures with high slump, the aggregate will segregate from the mortar and paste and may cause blocking in the pump lines.
