The objective of this investigation was to examine methods of testing round Steel Fibre Reinforced Concrete (SFRC) panels to obtain empirical estimates of post-crack load capacity under point loads. The performance of steel fibre reinforced concrete panels under point loads is of interest because...
The paper presents an experimental and theoretical study on the cracking behaviour of concrete beams having longitudinal tension reinforcement and various combinations of volume and aspect ratio of steel fibers. Five full-scale beams with a concrete compressive strength of 42 MPa were tested. The...
The paper presents results of pilot trials of using the focused ion beam (FIB) technique in the framework of methods for assessment of micromechanical properties of cementitious composites. FIB is already being used in other applications, namely for the purpose of micromachining ( e.g. repairs of...
