Early Age Properties of Portland Cement Pastes Investigated with Ultrasonic Shear Waves and Numerical Simulation (preprint)

Description:

In this paper, the correlation of reflection loss measured by an ultrasonic shear wave reflection method and the microstructure in cement-based material is investigated. Three cement pastes (Portland cement type I) with different water-cement ratios (0.35, 0.50 and 0.60) cured at 25 °C were examined. The ultrasonic shear wave reflection...

A Micromechanical Model for Characterization of Cement Paste at Early Age Validated with Experiments (preprint)

Description:

The gradual evolution of the material properties of a cement-based material, i.e. the stiffness of cement paste, is the result of the continuous change of the microstructure with the progress of the hydration process. Based on an existing micromechanical model for the simulation of the shear and elastic modulus of...
