Abstract
The purpose of this study is to investigate experimentally the effects of aspect ratio of polyethylene fiber on the compressive strength and tensile behavior of alkali-activated cementless composite. Two mixtures were determined according to aspect ratio values of polyethylene fibers, and the compressive strength and tension tests were performed. Test results showed that the effect of aspect ratio of fiber on the compressive strength was negligible and the tensile strength, ductility, and number of cracks of the mixture including the fiber with high aspect ratio were higher than those of the mixture including the fiber with low aspect ratio. On the other hand, the crack spacing and crack width were low in the mixture including the fiber with high aspect ratio.
