Pickup Velocity for Pneumatic Conveying powderbulksolids

The velocity of the air necessary to convey a material in suspension flow depends mainly on the particle properties of size, shape, and density. For fine powders the minimum conveying air velocity required will be in the region of 2000–2400 ft/min; 2000–2200 ft/min for cement; and 2200–2400 ft/min for fly ash.

The air entrained concrete has a whipped cream effect that allows slump reduction. Engineers take advantage of this slump reduction to further reduce the water-to-cement ratio in the concrete which can increase the strength of the concrete. Strength of air entrained concrete reduces 5 percent for every 1 percent of entrained air.
