Relationship between cube and cylinder compressive strengths of mortar used for ferrocement

Abstract

In this paper the relationship between cylinder and cube compressive strengths of ferrocement and the influence of wire mesh on such relationship was fairly studied. Different mortar mixes having different compressive strengths were attempted, and for this purpose a total of 108 specimens were tested in the laboratory.  The influence of wire mesh on mortar compressive strength was found to be not important, except in cubes reinforced with wire mesh perpendicular to direction of loading. Strength enhancement was due to the difference in mode of failure of specimens. The size of specimen seem to have an influence on compressive strength of mortar contain wire mesh. In general, the ratio of cylinder to cube mortar specimen is close to 0.94, this ratio can be used for the design of thin ferrocement sections. For thick sections, it is better to take the effect of any wire mesh perpendicular to the direction of loading. This paper gives an equation for calculating cylinder compressive strength for this case.
