Specifications

Specifications include, but are not limited to:An apparatus that measures the air-void system of freshly mixed concrete by the sequential pressure method, known as the Super Air Meter and associated necessary testing accessories and case, described as follows, from AASHTO TP 118:Super Air Meter: The Super Air Meter package with case shall be manufactured by Super Air Meter LLC. No substitutions shall be allowed.The Super Air Meter is a device consisting of a measuring bowl and cover assembly as described below. The operational principle of this meter consists of sequentially equalizing known volumes of air in a sealed air chamber, at a series of known pressures, with the unknown volume of air in the concrete sample placed in the measuring bowl. A digital pressure gauge with 0.01 psi (0.07 kPa) accuracy shall be used. Digital gauges with maximum pressures of 50.0 psi (344.7 kPa) have been used satisfactorily. The digital gauge shall be able to compute and report the air content within 0.1 percent and the SAM number to 0.01 psi (0.07 kPa). Measuring Bowl: The measuring bowl shall be essentially cylindrical in shape, made of steel, hard metal, or other hard material not readily attacked by the cement paste, having a minimum diameter equal to 0.75 to 1.25 times the height, and a capacity of at least 0.20 ft3 (5.7 L). It shall be flanged or otherwise constructed to provide for a pressure-tight fit between the bowl and cover assembly. The interior surfaces of the bowl and surfaces of rims, flanges, and other component fitted parts shall be machined smooth. The measuring bowl and cover assembly shall be sufficiently rigid to limit the expansion of the apparatus assembly to not more than 0.1 percent of air content on the indicator scale. Cover Assembly: The cover assembly shall be made of steel, hard metal, or other hard material not readily attacked by the cement paste. It shall be flanged or otherwise constructed to provide for a pressure-tight fit between bowl and cover assembly and shall have machined-smooth interior surfaces contoured to provide an air space above the level of the top of the measuring bowl. The cover shall be sufficiently rigid to limit the expansion as prescribed for the measuring bowl.
