Concrete is a heterogenous multi-phase and multi-scale material that is difficult to model and understand due to its heterogeneity. Thus, knowing the properties and modelling concrete in different scales is essential to predict properties and fracture. Most of the research has been focused on meso scale, or the methods available to model and predict micro-scale properties are not linked to experimental methods, so properties for microscale cannot be derived and it is onerous to validate such methods. Considering the above constraints in the multi-scale modelling of concrete, the book covers different modelling techniques of scales of concrete - macro, meso, micro/nano and molecular level, characterising mechanical properties and parameters required for modelling using macro and micro level experiments and linking these levels using analytical and numerical methods to upscale results from micro to the macro level. Covers the multiscale nature of concrete and different characteristics of concrete at macro, meso, micro, nano and atomic scalesIncludes finite element modelling of concrete at different length scales and advanced constitutive models of concrete and its constituents from nano to macroscalesSurveys state-of-the-art experimental techniques to obtain mechanical properties of concrete at various spatial scalesIncludes: numerical and analytical homogenisation methods to upscale and predict the macroscopic behaviour of concrete; advanced molecular dynamics simulations of concrete constituents at the atomic and nanoscale
