摘要
一、引言利用超声和回弹综合评定混凝土的抗压强度是近些年普遍采用的方法。它的测量精度和可靠性已被世界公认。然而由于影响混凝土抗压强度的因素较多,目前我国生产的超声仪和回弹仪只能给出间接物理参数声肘和回弹值,许多换算和修正需人工脱离现场才能完成。并且要求使用者必须具备一定文化和技术水平。
This apparatus is developed by using microprocessor technique with chipmicroprocessor. It can be used directly to display compressive strength and waveshape parameters of reinforced concrete structure being measured. The statisticalerror of the device for measuring strength (Beijing area) is: less than 4% forspecial model; less than 14% for common model. The reading error of amplitude is less than 0.1 dB.
