β¦ Synopsis
Moisture flow in porous media is the driving force behind early age drying shrinkage. Fracture in the interfacial transition zone (ITZ), between cement paste and aggregate-inclusion, is related to restraint caused by, among others, aggregates that obstruct free deformation of the paste. Environmental Scanning Electron Microscope (ESEM) test results are used as a base for the developed method for measuring shrinkage deformations during drying. Modeling of moisture flow in the heterogeneous samples is numerically performed with Lattice Gas Automata (LGA). Fracture coupling of the LGA and Lattice Fracture Model (LFM) requires coupling with ESEM tests regarding shrinkage coefficient.

Lattice gases, one class of cellular automaton model, are increasingly under investi$ation as a highly parallel means of simulating given partial differential equations. We examine stochastic lattice gas simulations, turning our attention particularly toward diffusive processes: nonlinear diffusion,

A class of lattice gas automata giving rise to diffusion at the macroscopic level is investigated both analytically and numerically. We focus on the non-equilibrium properties of the automata and, in particular, on the appearance of algebraically decaying long-range fluctuation correlations when the
