摘要: This paper describes experimental research to study the influence of rice husk ash and polypropylene fibres different lengths (6 24 mm) on residual fracture mechanical behaviour high-strength concrete (HSC). The evolution properties with temperature (room temperature, 100°, 300°, 500° 700°C) was analysed in various HSCs compared a non-reinforced reference concrete. pore level also studied subsequently effect adding HSC preventing spalling at high temperatures. Concrete ductility through characteristic length concrete, as increases Further other materials used this did not reveal any environmental problems.
