Gan, Y. (author), Romero Rodriguez, C. (author), Schlangen, E. (author), van Breugel, K. (author), Šavija, B. (author)This study presents an experimental investigation of the rate-dependent mechanical properties of cement paste at the microscale. With the use of a nanoindenter, micro-cantilever beams with the size of 300 μm × 300 μm × 1650 μm were loaded at five different strain rates from around 10<sup>−6</sup>/s to 10<sup>−2</sup>/s until failure. It is...journal article 2021

Gan, Y. (author), Romero Rodriguez, C. (author), Zhang, Hongzhi (author), Schlangen, E. (author), van Breugel, K. (author), Šavija, B. (author)This paper presents a method to numerically investigate the microstructural effect on the creep behavior of cement paste at the microscale. The lattice fracture model is extended to consider local time-dependent deformations of calcium-silicate-hydrate phases in the cement paste by imposing local forces. The term “experimentally informed...journal article 2021
