ASSESSMENT OF THE COMPRESSIVE STRENGTH OF CONCRETE BY THE SONREB TESTS: CASE OF THE POLE MOSQUE OF ORAN

The non-destructive evaluation of concrete is a vital part and an active and interesting field of research which can be a fundamental step in the process of heritageization of contemporary architecture, especially for the new large mosques in Algeria. The present study consists of the assessment of the concrete structure of the pole mosque of Oran by applying a protocol of non-destructive testing of the compressive strength based on the combination of two tests of the SonReb approach; ultrasonic pulse velocity (UPV) and rebound index (RN). This method not only makes it possible to check the physical state of the structure, but also to collect the information necessary to predict the possibility of use in the future. The results of the experimental tests obtained indicate a very acceptable quality of the concrete of the pole mosque of Oran.
