The C 3A content shall be calculated by the formula: C 3A = 2,65 A – 1,69 F (see 5.2.1).h Until the test method is finalised the C 3A content of clinker (see 5.2.1) shall be determined on the basis of the analysisof clinker as part of the manufacturer's Factory Production Control (EN 197-2:2000, 4.2.1.2).iAppropriate test method chosen by the manufacturer.23
