Abstract:Tensile, fiexural and compressive tests were conducted on mortar specimens reinforced with different lengths and volumes of steel and glass fibers. The tensile or flexural strength of reinforced specimens was at most two to three times that of plain mortar while the corresponding strains or deflections were as much as ten times that of mortar. The stresses and strains at first cracking were not significantly different from those of plain mortar. The values of the modulus of elasticity and the extent of nonlinearity were observed to depend on the methods of deformation measurement. Extensive microcracking was observed on the surfaces of failed flexural specimens indicating a significant contribution of the matrix even after the first cracking. For steel fiber reinforced specimens, the peak loads and deformations appear to be linearly related to the fiber parameter: Vf L/D. After failure, steel fibers pulled out while most of the glass fibers broke.
