New Generation Cementitious Composites with fibres – properties and application
Languages of publication
The paper presents the properties of new generation cementitious composites with fibres, such as “bendable concrete” (ECC, Engineered Cementitious Composites) (plastic, not brittle but resistant to cracking material) with the addition of polyvinyl alcohol (PVA) fibres, high performance concrete (HPC) with glass fibres, reactive powder concrete (RPC) (characterized by ultra-high compressive strength, above 200 MPa) with short steel fibres. The detailed characteristics of the composition of the cement matrix and the role of fibres in the formation of the composite properties are described. Various applications of the composites as structural and architectural materials are also given.
