长龄期混凝土超声回弹综合法测强技术的研究

在对旧建筑物的鉴定加固过程中，常遇到长龄期混凝土的测强问题，在利用非破损方法检测长龄期卵石混凝土强度方面，国内外研究报道较少。本文利用超声回弹综合法对自然养护条件下长龄期卵石混凝土预留试块进行了测试，建立了超声回弹综合法测强曲线，并对测试结果进行了分析，对于长龄期混凝土测强技术的研究和应用，具有一定的参考价值。

Study of Long-time concrete strength-testing technique with super-acoustic reflection

During the course of reinforcing old architecture,it is a common practice to test the its strength and consolidation degree.On the condition that without destroying the object,this paper intends to introduce a more comprehensive way by using super-acoustic reflection after a practical analysis of several strength-testing curves made to the experimental old buildings natural cure.It is no doubt this technique values a lot and it will make up for the blank of domestic relevant fields.
