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
Concrete compressive strength does not depend on the full hydration of its cement particles but essentially on their closeness 10 11 In a concrete having a water cement ratio lower than 0 42 hydration stops when there is no more water to hydrate the cement particles Below this critical value of 0 42 very fine cement particles can be fully hydrated but only the surface of the
