摘要
根据合肥地区常用材料,制作了不同强度等级、不同龄期混凝土试块,测量试块回弹值、超声波速值以及抗压强度值,在对国家超声回弹测强曲线在合肥地区使用适用性分析的基础上,建立了合肥地区超声回弹测强曲线,验证结果表明混凝土强度推算精度能较好地满足工程要求。
According to concrete construction feature in Hefei,concrete block is made in different strength degree and ages of concrete and the value of rebound,ultrasonic and strength is measured.Based on the applicability analysis of national ultrasonic rebound curve and engineering practice,local measurement ultrasonic rebound curve in Hefei is established and applicability that can be used in Hefei is proved by engineering practice.
