The particular mechanical properties of extruded steel fiber reinforced concrete (SFRC) has been discussed in an earlier paper. This paper is specifically concerned with the properties of extruded glass fiber reinforced concrete (GFRC) mortars. It is shown that the mechanical behavior of extruded GFRC is substantially different than that found with a conventional GFRC casting process, as was similarly found in the case of extruded SFRC. The response of extruded GFRC is also found to be substantially different from expected patterns of behavior which were derived from the investigation of extruded SFRC. These differences are primarily a reflection of the brittle nature of glass fibers as compared to those of steel.
