Additional tests of plain concrete were performed, where in addition a cylindrical compressive strength and modulus of elasticity were determined. Cylindrical compressive strength and modulus of elasticity tests were performed on cylinders with a diameter of 150 mm and a height of 300 mm. Based on 6 test specimens, the average cylindrical compressive strength was 48.85 MPa and the average modulus of elasticity based on 3 test specimens was 27.13 GPa.
