Residual compressive strength of plain and fiber reinforced concrete after exposure to different heating and cooling regimes

The article investigated the impact of different cooling regimes on the response of both plain and fibre reinforced concrete (FRC) after heating. A total of 256 standard concrete cylinders of normal strength concrete (NSC) and high strength concrete (HSC) were tested in compression after heating at 200 °C, 400 °C, and 600 °C. For each concrete grade, 32 specimens were prepared without fibres while 96 cylinders had fibres (steel, polypropylene...
