A Simple Method For Evaluating Elastic Modulus Of Refractories At High Temperatures

A new experimental procedure is presented for evaluating the elastic modulus of refractories at high temperatures. The method is based on flexural resonance after excitation by an impacting ball. A great experimental simplificaiton is introduced by using standard three point bending supports instead of a wire suspended sample, and an acoustic microphone as a non-contacting transducer. It is shown that the distance between support points has a negligible effect on the experimental results.
