This paper reports about the outcomes of small-scale laboratory tests on Vienna brick masonry and its components aiming at revealing the physical behavior of this type of historical brick masonry under earthquake loads. From historical buildings, which were constructed in the period between 1850 and 1918 (so-called “Gründerzeit”) in the City of Vie...

In this paper, a multiscale model for the prediction and, finally, optimization of mechanical (elastic) and thermal (heat conductivity) properties of porous building materials is presented. These technical composites are characterized by the increase of porous space in the respective material system, resulting in a reduction of Young’s modulus, on...

In this paper, a multiscale model for prediction and, finally, optimization of elastic and thermal properties for heat-insulating concrete based on foam-glass granulate is presented. This cement-based material is characterized by the partial replacement of the aggregate phase (sand, gravel) by foam-glass granulate. This replacement results in a red...

Based on the investigation of fiber influence on workability of self-compacting concrete (SCC), tests were carried out on two series of SCC rectangular simply supported beams, which were made of hooked steel fibers reinforced concrete with or without stirrups, subjected to four-point symmetrically placed vertical loads. The major test variables are...

Metamorphic waste can cause much damage to the environment and so the partial substitution of Portland cement with metamorphic rock waste to produce environmentally-friendly cement/concrete has been suggested. In the present study, the pozzolanic reactivity of metamorphic rock waste was investigated and the possibility of the partial replacement of...
