Sustainable Composites for Fire Protection of Building Structures

Popis výsledku v původním jazyce

The fire protection and fire safety of buildings is an indispensable part of nowadays construction engineering. The passive component of integral fire protection system involves among others also fire resistant construction elements which protect loadbearing structures made from concrete, steel or wood against the fire attack. Properly designed cementitious composites in form of boards and tubes are frequently used for this purpose. Traditionally the thermally resistant composites are based on aluminous cement as principal binder; unfortunately the production of aluminous cement is highly energy consuming. Historically these composites were reinforced by asbestos fibres which are nowadays banned for its carcinogenicity. The present paper deals with novel composites which rise the mentioned challenges including the reduction of production energy consumption and natural resources demand. The binding system consists of aluminous cement and selected active mineral admixtures – ground granulated blast furnace slag and coal fly ash – which reduces the aluminous cement consumption. The basalt fibres are used as adequate substitute of asbestos fibres. The residual mechanical properties of composites of varying composition subjected to thermal load were determined and helped for selection of proper mix design for fire resistant construction elements.
