This Standard specifies the method for determining the air content of fresh concrete through reduction of pressure in air chamber.<\/p>\n
\nThis Standard is applicable to concrete made with ordinary aggregate of which the maximum aggregate size is 40 mm or smaller.<\/p>\n
\nIt is not applicable to concrete made with porous aggregate such as artificial lightweight aggregate for which the aggregate correction factor cannot be accurately determined.<\/p>\n
\nThe water-column method is provided in Annex A (informative).<\/p>\n
\nNOTE 1 The test method specified in this Standard employs the principle of Boyle\u2019s law.<\/p>\n
\nNOTE 2 The air chamber method is carried out either with or without water injection.<\/p>\n
\nNOTE 3 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.<\/p>\n
\nISO 1920-2 : 2016 Testing of concrete \u2014 Part 2 : Properties of fresh concrete (MOD)<\/p>\n
