Project description

Concrete freeze-thaw durability is prominently linked to the air void system within the concrete. Concrete pavements in Kansas undergo repetitive freeze-thaw cycles. Total air content measurements currently used on fresh concrete do not provide any indication of the air void size distribution. The Super Air Meter (SAM) addresses this issue by providing the air content and an additional number, the SAM number, which is claimed by the manufacturer to correlate to the concrete hardened air void spacing factor.
