title = "Micromechanical modelling of cement paste using X-ray computed tomography and statistical nanoindentation",
abstract = "This work proposes a new method for micromechanical simulation of cement paste based on a combination of statistical nanoindentation and XCT technique without the need for explicit identification of distinct phases. A linear relationship between the greyscale level and local Young{\textquoteright}s modulus was assumed and verified by the two-sample Kolmogorov-Smirnov statistic. Based on this assumption, the fracture behaviour of a digital cubic volume (100 μm) under uniaxial tension was simulated using a lattice fracture model. The proposed method was compared with the results obtained from a approach used previously by the authors in which discrete phases were considered. The two methods show similar crack patterns and stressstrain responses. The proposed method is regarded more promising as it captures also the gradient of material properties within the discrete phases. ",
