Description
  • The paper summarizes the results of the development of special fibre reinforced concrete intended for the explosion resistance applications. An experimental research aimed at contributing to understanding of the effect of different type of reinforcement on the behaviour of HPFRC subjected to the blast load was carried out. The fine grained concrete matrix has been reinforced by various types of dispersed fibres – metallic, mineral and polymer - with different length (6 – 55 mm) (0.24 – 2.16 in.) and their combination, while the volume content (3 %) of fibres was kept. Mechanical and explosion tests were performed on prismatic and slab shaped specimens and the effect of different kinds of reinforcement on blast resistance and mechanical performance of the concrete samples has been evaluated. Accelerations of the specimens within blast load were captured. The material characteristics and explosion test data obtained were used for creation of finite element model in LS-DYNA. Numerical investigation resulted in the design of concrete elements for population protection, which shall resist the explosion defined by type, size, weight and placement of the charge.
