Acoustic emissions and electric signal recordings, when cement mortar beams are subjected to three-point bending under various loading protocols
Two experimental techniques are used study the response of cement mortar beams subjected to three-point bending under various load¬ing protocols. The techniques used are the detection of weak electric current emissions known as Pressure Stimulated Currents and the Acoustic Emissions (in particular,...
