Double-curved panels produced in a flexible mould with selfcompacting fibre-reinforced concrete

The number of applications with thin flat, curved or double-curved elements often produced as architectural elements for façades is rising fast. If the repetition factor of the elements is limited, which is often the case in free-form architecture, the high number of unique moulds makes this type of architecture economically less viable....

How to measure path length?

Path length measuring is a relevant engineering problem. Leonardo Da Vinci designed for the military appropriate equipment, the podometer, to do so. Modern equipment such as step meters and map meters are quite similar to Da Vinci?s design, despite geometrical statistical - stereological - methods based on theorems of Cauchy and Buffon that were...

Self-compacting fibre reinforced concrete applied in thin plates

Floor panels produced with traditionally vibrated concrete are relatively thick due to the need to reinforce concrete and consequently, heavy. Without the need to place rebars in panels and by applying self-compacting fibre reinforced concrete (SCFRC) the production process becomes more efficient. Fibres improve the performance of concrete by...
