Over the years many different constitutive models have been developed to describe the behavior and failure of concrete. In order to calibrate and validate any constitutive model experimental data of sufficient quality covering different experimental setups are required. Ideally, the calibration of concrete requires unconfined and confined compressive tests as well as direct or indirect tension tests. Damage evolution and softening behavior can only be calibrated if post-peak data are available. We present a large collection of concrete tests where all specimens are cast from the same batch and most were tested at a relatively late age. In total 128 three-point bending tests of 400 day old beams of four sizes, notched with four relative notch depths and un-notched, 12 standard ASTM tests for modulus of rupture with 31 and 400 day old beams and 24 uniaxial compression tests on 31 and 400 day old cylinders are available. Afterwards, 105 specimens were cut from the remaining shards to carry out additional extended investigations: 12 centrally and eccentrically loaded three-point bending tests with 466 day old beams, 40 Brazilian splitting tests with 475 day old prismatic specimens of 5 sizes, 22 uniaxial compression tests with 470 day old cubes, 6 uniaxial compression (tension) tests with 950 days old cubes (prisms), 4 confined compression tests with 560 day old cored cylinders and 11 torsion tests with prisms. The nominal stress-strain curves are provided for all the specimens as well as the force displacement data.
