Sažetak
Shrinkage of cementitious composites is an unavoidable phenomenon which occurs right after the contact of cement and water, and it continues until late age. It is a complex phenomenon consisting of various types of shrinkage that occur due to different mechanisms. In early age it causes microcracks that form inside the composite because stresses exceed the strength value. Formed microcracks have a potential to grow into macrocracks. The presence of short fibres can restrain formed cracks and improve the properties of concrete in terms of durability. The aim of this work is to show the influence of the waste fibres on early- age properties of cementitious composites with the emphasis on autogenous shrinkage. Used fibres are alkali resistant glass, basalt, and carbon fibres obtained from a local producer of technical textiles.
