Comparison of Compressive Strength and Young’s Modulus of Cement Samples with Different Types of Aggregate

Abstract:

Several different types of aggregates were used for production of tested samples, namely: the standard sand of a fraction 0-4 mm, quartz sand of a fraction 0-0.4 mm, finely ground recycled limestone powder of a fraction 0-0.07 mm, finely ground recycled concrete of a fraction 0-0.13 mm (ground by Lavaris Company), and finally crushed bricks of a fraction 2-5 mm. The Portland cement CEM I 42.5 R produced in Radotín was used as a binder. Testing was carried out on prismatic samples of dimensions 40 × 40 × 160 mm. Compressive strength and static Young ́s modulus were measured for individual samples and these differed by the type of a microfiller and its amount.
