Note.: (*) The values of tensile strength resistance of the classes FC200 and FC 300, refer to tests carried out in specimen from 30mm diameter bars cast separate from the part. The chart below shows the values expected for tests carried out in specimen taken from bars in the medium section in relation to the gauge.
