摘要: Quite often, concrete in structures is likely to get exposed high temperatures, including an incident of fire. The strength-retention properties after such exposure are great importance terms the serviceability buildings. This paper presents experimental study on strength retention and impermeability aspects a set self compacting, high-volume fly ash mixes under elevated temperatures. Five selfcompacting with higher 60% level cement replacement fly-ash, designed effects range 200-800°C, physical, mechanical durability these assessed. assessment weight losses reduction compressive strengths cubes split tensile cylinders. characteristics assessed RCPT test results mixes. Performances compacting (SCC) at elev...
