The 2016 Missouri Concrete Conference, May 3-4 on the Rolla campus, will feature presentations covering steel or macro synthetic fibers in concrete; impact of air pollution control on fly ash; proper curing techniques and materials; soil stabilization and full-depth reclamation; new American Concrete Institute pavement construction guide; lithium silicate curing compound; floor slabs and toppings; practical applications of resistivity testing; the Super Air Meter
; city and county pavement management programs; and, Missouri Department of Transportation bridge girder specifications.
New from IFM ELECTRONICS, a sensor market leader, is a version of the established metris compressed air meter
for a variety of pipe sizes, up to and including 254mm internal diameter.
The ASTM C231-08 (2008) standard method was applied using a Type B air meter
(refer to Fig.
Delphi's new air meter
is a two-component device made of 30% glass-and mineral-reinforced PBT supplied by Ticona.
We also take the inexpensive and compact Dwyer 460 Air Meter
with us on every inspection, just in case we need a velocity or static-pressure measurement.
A hydraulic Cyclo Air meter
drive ensures smooth rotation of the drum for precise seed placement.
A modified version of the ASTM C231, Standard Test Method for Air Content of Freshly Mixed Concrete by the Pressure Method vessel, the Super Air Meter
(SAM) measures air-void spacing and air content of plastic concrete in about 10 minutes.
We realized that we'd been neglecting one tool--the Dwyer[R] 460 Air Meter
kit--and decided we should have spent more time explaining its versatility and the many things it can do.
