Název v původním jazyce

Elastic Properties of Hydrating Cement Paste Determined from Hydration Models

Popis výsledku v původním jazyce

This report attempts to apply elastic homogenization methods for the prediction of elastic properties of the microstructures of cement-based materials. The latter may be analyzed on four independent scales, based on a characteristic length criterion; C-S-H level, cement paste level, mortar level and concrete level. The report focuses on the cement paste level, where the majority of changes occurs during the hydration, captured by CEMHYD3D model. A new model of C-S-HLD and C-S-HHD evolution at the microscale is presented and validated with the results from porosimetry. Three elastic homogenization approaches are taken into account; analytical methods such as the Mori-Tanaka or the self-consistent scheme, the FEM with different boundary conditions, and the method based on FFT transformation. Several experiments from the literature are validated showing the potential of homogenization methods.
