Concrete roughness measurement

Concrete roughness is an important measurement during concrete repairing process. There are many devices working in industry which measure concrete roughness. Laser based devices are worldwide developed and applied. A different strategy is the use of mechanical devices which are more dust robust and cheap than laser born detectors. For laboratory purposes we create mechanical devices for concrete roughness, which detect the contour of the surface. Then an image processing system will help to transform the signal into the computer memory for precise evaluation. The system is robust, cheap and does not require complex calibration. User friendly software will calculate and evaluate the data instantly. The method is perfect for laboratory measurements.

Mechanical device for copying the concrete profiles

The mechanical device is constructed to copy the surface using many pins with diameter 0.8mm. This device is dust robust and does not require any calibration or special support. It can be applied on any surface and can measure roughness up to 100mm with 1mm precision. The image processing system includes VB programme for filtering and evaluation of the data.

Filtration process is applied and results are produced in pixels.

The final result shows the same profile structure and can be evaluated in MS Excel or any other system.

Also for more precise measurement, different features can be extracted using large data representation structure.
