禄丰地区混凝土实体测强曲线分析与验证

Analysis and Verifi cation on the Concrete Physical Strength Measures Curve of Lufeng Region

根据禄丰地区混凝土特点,制作不同强度等级的混凝土同条件养护试块,测试试块回弹值、超声声速值及抗压强度,分别用国家、昆明地区和禄丰地区的测强曲线进行分析验证,结果表明建立的禄丰地区测强曲线可以应用于禄丰地区混凝土实体检测。

According to the characteristics of concrete in Lufeng,concrete block was made in different strength degree under the same curing condition,and the value of rebound,ultrasonic velocity and compressive strength was measured. The concrete strength was analyzed and verified with countries,Kunming and Lufeng strength measures curve. The results showed that curve which was proved by engineering practice could be used in Lufeng.
