More2021-6-15 When making concrete, the compressive strength is normally controlled by the water-to-cement ratio, and tensile strength is boosted by additions, often steel, to make reinforced concrete. In other words, concrete is composed of sand (a fine aggregate), ballast (a coarse aggregate), cement (also known as a binder), and water (which is an additive).

MoreThe 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 ...
