Experimental Study on the Influence of Different Cooling Methods on Mechanical Properties of Concrete After High Temperature
为研究不同冷却方式对高温后的混凝土力学性能的影响,文中通过抗压试验和三轴压缩试验,围绕不同冷却方式对混凝土力学性能的影响进行分析.结果表明,800℃时,经自然冷却、喷水冷却和浸水冷却的试件质量烧失率分别为11.84%、12.72%和13.44%,抗压强度分别为12.07、10.51 和9.19 MPa;围压为4 MPa时,三种冷却方式下试件三轴强度分别为35.84、30.21、24.63 MPa.自然冷却条件下,混凝土强度明显优于其余冷却方式;冷…查看全部>>
In order to study the effects of different cooling methods(natural cooling,spray cooling and water immersion cooling)on the me-chanical properties of concrete after high temperature,the impact of different cooling methods on the mechanical properties of concrete was ana-lyzed by compressive test and triaxial compression test.The results show that at 800℃,the mass loss rates of specimens under natural cool-ing,water spray cooling and water immersion cooling a…查看全部>>
