摘要
随着温度的升高,钢筋混凝土结构各项性能将会发生明显编号,混凝土会因高温作用而爆裂,钢筋强度会显著降低,结构变形明显增大。通过对四组C25混凝土试块进行的高温试验,然后冷却到常温后2h后进行抗压强度试验。对有、无防火涂层的混凝土试块进行高温试验,结果表明防火涂层对混凝土具有明显的保护作用。因此对重要建筑物结构在高温环境中防火涂层的作用进行研究是非常重要的。
As the temperature increases, the performance of reinforced concrete structure will change significantly number of concretedue to high temperature and burst, steel strength is significantly reduced structural deformation increased significantly. By high temperaturetest of the four groups C25 concrete test block, and then cooled to room temperature, compressive strength test after 2h. For there is nofireproof coating of concrete block test results were compared, results showed that fire protection coating on concrete with a significantprotective effect. Therefore, the important role of the building structure in a high temperature environment, fire protection coating onresearch is very important.
