Sherzer, G. (author), Gao, P. (author), Schlangen, E. (author), Ye, G. (author), Gal, E. (author)Modeling the complex behavior of concrete for a specific mixture is a challenging task, as it requires bridging the cement scale and the concrete scale. We describe a multiscale analysis procedure for the modeling of concrete structures, in which material properties at the macro scale are evaluated based on lower scales. Concrete may be viewed...journal article 2017

Zhang, H. (author), Šavija, B. (author), Chaves Figueiredo, S. (author), Lukovic, M. (author), Schlangen, E. (author)This work aims to provide a method for numerically and experimentally investigating the fracture mechanism of cement paste at the microscale. For this purpose, a new procedure was proposed to prepare micro cement paste cubes (100 × 100 × 100 µm3) and beams with a square cross section of 400 × 400 µm2. By loading the cubes to failure with a...journal article 2016

Liu, D. (author), Heard, P. (author), Savija, B. (author), Smith, G. (author), Schlangen, E. (author), Flewitt, P. (author)In the present work, the microstructure and mechanical properties of Gilsocarbon graphite have been characterized over a range of length-scales. Optical imaging, combined with 3D X-ray computed tomography and 3D high-resolution tomography based on focus ion beam milling has been adopted for microstructural characterization. A range of small...conference paper 2015

Montero-Chacón, F. (author), Schlangen, H.E.J.G. (author), Medina, F. (author)The use of fiber-reinforced high-performance concrete (FRHPC) is becoming more extended; therefore it is necessary to develop tools to simulate and better understand its behavior. In this work, a discrete model for the analysis of fracture mechanics in FRHPC is presented. The plain concrete matrix, made of mortar and coarse aggregates, is...conference paper 2013

Xuan, D. (author), Schlangen, H.E.J.G. (author), Molenaar, A.A.A. (author), Houben, L.J.M. (author)Fracture properties of cement treated demolition waste were investigated using a lattice model. In practice the investigated material is applied as a cement treated road base/subbase course. The granular aggregates used in this material were crushed recycled concrete and masonry. This results in six different types of phases in the mixture:...conference paper 2013
