Abstract
Mechanical properties of concrete mixtures with AR glass fibers are studied. Two types of concrete mixtures representing a lean mixture and an HPC (High Performance Concrete) mixture are used. Two types of AR Glass fibers High dispersion (HD) and High Performance (HP) with different sizing formulations to help with distribution, bonding and durability were considered. High dispersion (HD) AR Glass fibers of several different lengths were used to evaluate the effect of fibers which disperse thoroughly throughout the mixture. These were compared with High Performance (HP) type AR Glass fibers which maintain the bundle characteristics throughout the mixing and casting and are designed to help with long term strength and ductility. A formulation based on the R-Curves is presented to measure the contribution of the fibers to the overall toughening mechanism.
