- 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.
