Ultrasonic Pulse Transmission Tests: Datasets - Test Series 4, Cement Paste at Early Stages

The test series was created to receive information about the impact of the behaviour of the piezoelectric shear wave sensor on the measurement results of ultrasonic transmission tests performed on cement pastes at early stages. The approach for the test series was to vary the parameters water-cement-ratio and pulse-width. This results in a two-dimensional test parameter grid (water-cement-ratio versus pulse-width). Tests were performed for each grid point in order to receive information needed to optimize the pulse width for the shear wave sensors, but also a possible dependency between material behaviour and pulse-width. The materials tested were blends from ordinary Portland cement and tap water. The test methods used were ultrasonic pulse transmission method with combined compression- and shear wave measurements, gravimetric density tests (fresh paste density, solid specimen density) and hydration temperature tests. All test data and metadata are summarized into datasets using GNU Octave's open binary file format.
