This work proposes an original and active method for non-destructive testing of concrete and can also be used for other building materials. The proposed method includes the successive steps of: drilling holes into samples of building material with use of rotation or percussion drilling machine and simultaneously determining the power consumption necessary for drilling; strength determination of building material by destructive failure of samples; obtaining a positive empiric correlation between the power consumption necessary for drilling and determined strength values of material; control during drilling the holes in structure material being tested and simultaneously determining the power consumption necessary for drilling; determining the actual strength of structure material being tested by use of correlation between power consumption and material strength values derived in testing process. The application of the method makes strength determination of building materials simpler and faster and also increases the accuracy of testing.
