Testing fresh concrete - Air content. Pressure methods Ingestion-build-67170 Who is ISO 898-1 -This 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.
