### Average Compressive Strength - an overview | .

After 28 days an average compressive strength of 38 N/mm² was desired to obtain a concrete strength sufficient for certain applications. The cement-reduced concretes must have sufficient workability. Therefore the table-test flow value according to DIN EN 12350-05:2009-08 was chosen to be 550 mm. The cement-reduced concretes are intended to be used for interior structures (exposure .
