Pumping Air Entrained Concrete › uploads › 1/1/8What does this Mean for Concrete? •Air Content and SAM testing after pumping may not be representative of the hardened concrete. •If this is true then concrete should not be rejected for low air or high SAM Number after pumping. •It appears that sampling the concrete prior to pumping is a good indicator of the air void system in the
Loss of Air Content in Pumped Concrete — What, why, & how ... › concrete-tips › loss-of-air CachedIt is normal to find a loss of about 0.5 to 1.0 percent air as concrete is conveyed through a pump. However, with long boom pumps, having the boom in an orientation with a long, near-vertical downward section of pipe, the air content at discharge may be less than half of that of the concrete going into the pump hopper.
Air void systems in pumped concrete › app › uploadsof air before and after a concrete pump. • Pumping was observed to modify the air content and SAM Number in both the lab and the field testing. • Based on the hardened air void analysis, freeze thaw testing, and changing SAM Number over time, the air seems to return to the concrete with similar volume and spacing as was in the concrete
UNDERSTANDING THE PUMPABILITY OF CONCRETE › cgi › viewcontentthe use of pumps to transport concrete generally results in a loss of air ranging anywhere from one to three percent (Hover, (6), Boulet, (7), Chouinard, (5), Du and Folliard, (8)). It has also been shown that the resulting air-void system possesses no Marc Jolin, Dennis Burns, Benoît Bissonnette, Frédéric Gagnon, Louis-Samuel Bolduc 14 2009 SAFETY PROCEDURES - American Concrete Pumping Association › sites › concretepumpersA concrete pump can supply much more pressure than air. The compressed air will only continue to be compressed and store very dangerous levels of energy and could eventually explode and cause severe injury to anyone in the area.
