INTELLIGENCE ULTRASOUND-RESILIENCE COMBINATION INSTRUMENT FOR THE ASSESSMENT OF CONCRETE

    Graphical Abstract
    • Abstract
  • 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.
