Concrete strength tester
Detection object:
Railway, transportation, water conservancy, construction, etc.
Test content:
Concrete structure: internal strength of the structure
Test items
Concrete strength tester
STL-CMT
Product Highlights
High test accuracy:
Based on the elastic wave theory, the test error of the dynamic elastic modulus of concrete is less than 2%;
Creatively use dynamic elastic modulus as the medium, and use Sigmoid curve to return the compressive strength, and the calculation result is stable;
Affected by structural form, steel bar, etc., can be modified;
Through standard test block calibration under the same conditions, the detection accuracy can be further improved.
Powerful:
Can detect the strength of concrete surface and deep layer.
Wide testing range:
It is suitable for different concrete structure sizes from 0.1m to 100m, and can detect the strength of concrete at different ages.
High reliability and durability
product description
This product is mainly used for railway, transportation, water conservancy, construction and other large-volume concrete structures for rapid and accurate strength non-destructive testing. This product uses elastic waves as a medium to detect the internal strength of the structure. It has unparalleled advantages of ultrasonic detectors and rebound meters.
Testing Mass Concrete Structures
Deep testing and wide range
High test efficiency
Communication Law
When there is only one test surface, one-sided propagation method can be used for
testing.
When the wall thickness of the structure is thin, P wave can be used.
When the wall thickness of the structure is very thick, R wave test is needed.
The propagation velocity of the elastic wave in the concrete is picked up by the sensor, and the elastic modulus and strength of the concrete are calculated. The
specific test methods are:
Through method
When there are two test surfaces, it is preferred to use, the test range is light, and the test accuracy is also high
