New perspective material for building envelopes

Popis výsledku v původním jazyce

Thin-walled fibre-cement elements are widely used in residential and industrial buildings for their appearance and durability. Because they are made of light-weight materials, they are mostly used as cladding elements for façades of multi-storey buildings exposed to hard external conditions. Nevertheless, there are still demands from architects and building companies to decrease their weight for reducing manufacturing, transport and assembly costs. In one part of our research light-weighing possibilities of standard composition were evaluated by means of porous structure creation. In the second part the standard aggregate was substituted with available kinds of light-weight porous aggregates in a certain part or in a whole volume. As the limit criterion there was maximal particle size 1 mm for spraying of fibre-cement mixture by means of special air pressure equipment. From the range of possible fillers with different material properties granulated expanded glass worked the best. This paper brings not only a summary of laboratory experiments but also examples of successful realizations such as balcony panelboards, façade elements, bridge structure cladding elements or bulk flower pots. Even though these are not structural elements, it was necessary to evaluate also strength characteristics and resistance to environment for their durability in certain applications.
