Systematic research on compucrete can shed light on some controversial issues in concrete technology

Realistically simulating fresh and hardening cementitious materials renders possible understanding controversial issues existing in the field of concrete technology. The experimental studies on the impact of the interfacial transition zone (ITZ) on permeability of concrete reveal two controversial results. The first involves the concept of...

Porosimetry by DraMuTS applied to DEM-produced cementitious materials

Porosimetry of matured cementitious materials is of hiigh interest, because durability is governed by the capillary pore network structure. Experimental approaches are time-consuming, laborious and thus expensive. Fast developments in computer technology make it nowadays possible quite realistically producing cementitious materials in virtual...

Shape characterization of concrete aggregate

As a composite material, the performance of concrete materials can be expected to depend on the properties of the interfaces between its two major components, aggregate and cement paste. The microstructure at the interfacial transition zone (ITZ) is assumed to be different from the bulk material. In general, properties of conventional concrete...
