APPLICATION OF FIBRE CONCRETE WITH RECYCLED AGGREGATE IN EARTH STRUCTURES

This paper deals with fibre concrete made of recycled masonry or concrete aggregate which substitutes fully the natural aggregate in terms of its characteristics. The combination of recyclable building waste, synthetic fibres and binder yields a novel composite material with limited, but well utilizable properties for building structures. The application of this composite material is ensured by the synthetic fibres, which along with the other components constitutes the tough structure of the composite favourable especially under tensile loading due to its high ductility. The paper also describes application of the presented composite material in earthwork and gravity dams. These efforts help to reuse building waste and increase resistance of gravity dams to overspill, which are in accord with the sustainable building development.
