★ Instrument Introduction

CABR/PI-2 tensile strength tester is a specialized instrument for testing the compressive strength of concrete based on the national industry engineering standard "Technical Specification for Testing Concrete Compressive Strength by Tensile Strength Method".CABR/PI-2The pull-out device adopts the concept of mechatronics design, powered by lithium batteries, driven by micro motors, controlled by microprocessors, and its user-friendly appearance makes its operation simpler, faster, and more intelligent. This instrument is equipped with a dedicated drilling and grinding head for drilling standard core samples, which can eliminate the influence of testing surface factors and ensure the accuracy of measurement results.

★ Characteristics of "Pull off Method" Detection Technology

Pull off method "is a newly developed micro damage concrete strength testing technology in recent years, which combines the tensile strength of pull off specimens with that of concrete150mm×150mm×150mmThe correlation between the compressive strength of cubic specimens can be used to detect and estimate the compressive strength of concrete, which can replace specimens under the same conditions at the construction site. The "pull-out method" detection technology ensures the accuracy of detection and the accuracy of detection results. Compared with other current concrete strength testing technologies, there have been substantial improvements.

The external dimensions of the pull-out specimen (φ)44mm×44mm）Small, it can detect concrete structural components with dense steel reinforcement configuration. Pull off specimens do not require processing to avoid testing errors caused by specimen processing; Compared with other current technologies for detecting concrete strength, it improves efficiency2~3Double; detectable10MPaConcrete strength at different ages (early age) and in areas with dense steel reinforcement.
