Concrete is possibly the most widely used man-made construction material in the world. Low cost, versatility and adequate compressive strengths are reasons for the popularity of concrete construction. In the present investigation various properties of polyproplene and steel fibre reinforced cementitious composites in their plastic state, which influence slipforming (Chapter 3), such as early age shrinkage (Chapters 4, 5) and uniaxial tensile strength (Chapter 6) are investigated, while properties of the same mixes in their hardened state such as compressive and tensile splitting strength are also determined (Chapter 9). Three new experimental apparatae were developed during this investigation - one for the determination of the tensile stress-strain curve of fresh concrete (Chapter 6) and two for the investigation of early age shrinkage cracking of fresh concrete (Chapter 7). Theoretical aspects relating to the obtained experimental results were also considered (Chapters 6, 8). The experimental data was analysed by a digital computer with the aid of five FORTAN 77 computer programmes which were written by the author specifically for this purpose (Chapter 10).
