摘要
火灾高温作用后,混凝土的强度将发生变化。通过试验,对影响混凝土强度的因素进行了分析,并建立了利用回弹法评定火灾后混凝土抗压强度的专用测强曲线及计算公式,为编制火灾后混凝土结构检测评估技术规程提供试验依据和数据。
Burned after the high temperature by fire, the compressive strength of concrete structure will change. This paper analyses the factor that affects the concrete by a series of experiments, and establishes the curve and the formula by a rebound method, these experimental data, curve and formula redound to the testing and evaluation technology of the concrete structure.
