Effect of Fire and High Temperature on the Properties of Self Compacted Compacted

摘要：

The use of self-compacted concrete increased significantly during the last few decades. Selfcompacted concrete exhibits significantly higher compressive strength than normal concrete, which allows structural members to carry higher loads. The influence of elevated temperature on the properties of concrete is important for fire resistance studies. Fire remains one of the most serious potentials hazardous to any building. In this study the effect of high temperature on the properties of self-compacted concrete (SCC) compared with the ordinary concrete (NC) was investigated. The effect of cooling technique on the properties of SCC and NC was discussed. The properties of SCC and NC were measured after exposed to 200, 400 and 600℃ for two hours. Results from these tests show that the mechanical properties decreased with increasing temperatures. The mechanical properties of SCC cooled gradually are better than that cooled suddenly by water.
