3D-Simulation

At Concrefy the focus of simulation is on young hardening concrete. Young concrete behaves, unlike matured concrete, in a way that the properties of concrete change significantly in time which adds more complexities to structural models.

An additional challenge for young concrete is its exothermic reaction that results in the development of heat. Depending on the environment, the heat distributed in the concrete continuum in space and time will differ. This difference results in uneven expansion and strains in concrete. Additional restraint in concrete is provided by the structural boundary conditions that could result in additional imposed strains. Concrete mechanical properties develop slowly in time. The imposed strains can lead to imposed tensile stresses exceeding the mechanical tensile strength of concrete leading to cracks.
