Abstract
A comprehensive experimental program on pullout and pullthrough tests of steel fibers from a cement-based matrix is described. Emphasis is placed on the accurate measurements of the pullout load versus end-slip response. Parameters included three different types of fibers (smooth, deformed, and hooked), three different mortar matrixes with low, medium, and high strengths, one cement-based slurry matrix, and additives such as latex, fly ash, and microsilica. The medium from which the fiber was pulled out included a control mortar mix without fibers, mortar mixes with 1, 2, and 3 percent fibers by volume, and a SIFCON matrix containing about 11 percent fibers by volume. For smooth fibers, five different diameters and three different embedment lengths were investigated. Experimental pullout load versus slip curves are needed to derive typical bond shear stress versus slip curves considered to be a property of the interface.
