Concrete Compressive Strength - an overview ...

The concrete compressive strength f c and the modulus of elasticity E c were tested according to the Australian Standards AS 1012.9 (1999) and AS 1012.17 (1997), respectively, using a servo-hydraulic testing machine with a range of 3000 kN. In order to obtain more accurate experimental data, the concrete compressive strength and modulus of elasticity were tested on the day of the beam test ...
