摘要
C2 0混凝土试块在 4 5 0℃高温下持续不同时间后自然冷却 ,再对其进行超声、回弹综合法及标准抗压强度试验 ,以探讨同一高温不同时间作用后混凝土强度的变化规律 。
Comprehensive method of ultrasonic testing and standard compressive strength test was used to deal with C20 concrete heated under high temperature of 450℃ with different time. The regularity of concrete strength with the same temperature and different time was studied and the relationship between nondestructive testing and standard compressive strength test was analyzed.
