Particulate structure and microstructure evolution of concrete investigated by DEM: Part 1: Aggregate and binder packing

Experimental approaches in concrete technology are time-consuming, laborious and thus expensive. Developments in computer facilities render possible nowadays realistically simulating the particulate structure and microstructure of cementitious materials. For that purpose, discrete element methods (DEM) are required because of more correctly...

Particulate structure and microstructure evolution of concrete investigated by DEM: Part 2: Porosimetry in hydrating binders

Durability of concrete in engineering structures is becoming more and more of a major problem. Research into such problems is complicated and expensive, however. Developments in computer technology make it possible nowadays realistically simulating cementitious materials and studying its pore network structure. In this paper use is made of the...
