Fibre reinforced mortars for cultural heritage protection

Popis výsledku v původním jazyce

The adding of natural fibres to mortar mixtures is arguably the most important ancient technology applied the world over for its ability to improve performance. Even though modern synthetic fibrous materials are replacing historical ones, natural fibres may still be a competitive option by virtue of their ecological and economic qualities. The paper presents selected results of comprehensive investigations into the behaviour of lime mortars modified with natural and synthetic fibres and fibrous particles. It summarizes technical data for fibre reinforced mixtures made of lime matrix, sand and natural fibres (goat and horse hair), fibrous particles (sawdust and grain husks), as well as polypropylene fibres. Observations are presented regarding the impact the fibres have on the physical characteristics of the resulting matured mortars. The results of mechanical tests illustrate the degree to which fibres influence mortar strength. A positive effect on tensile strength is documented in an example where such mortars are applied as reinforcing layers to lowstrength masonry. The effects of weathering were also tested on small uncovered areas of plaster layers applied to burnt clay roof tiles exposed to one year in an outdoor environment.
