Testing fresh concrete - Air content. Pressure methodsThis European Standard, a part of the BS EN 12350 series, describes two methods for the determination of air content of compacted fresh concrete, made with normal weight or relatively dense aggregate of maximum size 63 mm. The methods are not applicable to concretes made with lightweight aggregates, air cooled blast furnace slag, or aggregates with high porosity. Both methods employ the principle of Boyle Mariottes law. For the purposes of reference,
