Abstract:
The development of a virtual testing system is no small
task. It requires fundamental scientific research into
the physics, chemistry, and materials science of
concrete. The Virtual Cement and Concrete Testing
Laboratory consortium has identified three core
competencies that are being addressed: 1) prediction of
cement hydration behavior, 2) computation of the
rheological properties (i.e. flow behavior) of fresh
concrete, and 3) prediction of the mechanical properties
(elastic moduli, compressive strength) of hardened
concrete.
