After summarizing the criteria for a sound prediction model, we discuss in detail the theoretical justification of model B3, including the thermodynamic restrictions, reasons for using power functions, consequen

Werbekommunikation – ein Entwurf in research motivated by concrete nuclear power plant structures, and more recently by tall building fires and tunnel fires. First we review the mathematical modeling of heat transfer in concrete, including the effect of heat on cement hydration and the heating caused by early-age hydration. Then w

Numerical Analysis of Creep Problemshich is unconditionally stable, allowing arbitrarily increasing time steps as the stress changes fade out. The algorithm is first presented for a nonaging Kelvin chain and then extended to a solidifying chain and to a chain with general aging.

Moisture Transport in Concretend numerical techniques. The cases we cover include drying of a slab or half-space (under constant or variable ambient humidity), steady flux of moisture through a wall, and spreading of a hydraulic pressure front into unsaturated or self-desiccated concrete. The link between moisture transport and

Solidification Theory for Aging Effect on Stiffness and Basic Creepfferent ages at loading not to diverge with time from each other, which in turn rules out creep recovery curves with nonmonotonic decay. We also explain the problems with creep compliance models giving a relaxation curve that crosses to the opposite sign. We compare the behavior of a number of model
