Performance of high-strength fibre-reinforced concrete in dynamics
bookPart
Properties of concrete can be tailored by selecting its constituents, composition, production, and curing procedure. A historical overview of the development of high-strength fibre-reinforced concrete (HSFRC) is given. The role and contribution of the main constituents to the mechanical properties are described to illustrate the possibilities of controlling the concrete properties. Next, the strength and deformation capacity under static loading as a function of matrix and fibre properties is summarized. The principles of the dynamic response mechanisms, as described in Chapter 7 for ordinary concrete, are applied to HSFRC to predict the tendencies in rate effects. These are compared with test data on strength and deformation capacity given in the literature as well as the semiempirical equations for the dynamic increase factor on strength. The combination of data and knowledge on the dynamic response mechanisms reveals the main characteristics of HSFRC for tensile loading in dynamics. The dominant effect of fibre orientation on the postpeak response and the impact resistance of HSFRC is illustrated with a dedicated impact test, showing the damage development in time. © 2024 Elsevier Ltd.
