Tiivistelmä
The purpose of the thesis was to create a measurement system for HAMK Ohutlevykeskus. The commissioning company designed and created the test station for testing concrete beams, by applying force onto concrete. Force application onto concrete was performed by using a hydraulic jack, which was also provided by the commissioning company. The objective of the thesis was to measure the sound emitted by the concrete beam during loading.
The research question of the thesis was to define the possibility of recognizing the sound coming from the loaded concrete, to design a program that can detect the change in the sound and give an alarm when concrete breaks. The thesis examined alternative methods for performing this testing.
These methods were described and analysed in this thesis.
Based on the measurement results it was stated that the method used in this thesis was not the perfect solution, and general the flexural test was recommended. In the current state, the test station is unable to perform the general the flexural test. With additional improvements to the station this might become possible. Even though the station was able to perform the required tasks some adjustments were made. With all these complications, the objective of the thesis was achieved, and the program is ready for use.
