Abstract
|
The article at hand presents an investigation of the tensile behavior of high-strength strain-hardening cement-based composites (HS-SHCC) made with four different types of dispersed high-performance polymer fibers. In particular, high-density polyethylene (HDPE), poly(p-phenylene-terephthalamide) (aramid), as-spun poly(p-phenylene-2,6-benzobisoxazole) (PBO) and high-modulus PBO fibers were examined in respect of their reinforcing effect in a high-strength, finely grained, cementitious matrix. Besides the tension experiments at the composite level, single fiber pullout tests were performed for a micromechanical characterization of each composite material. Furthermore, contact-angle measurements and microscopic investigations were carried out to assess the fibers ability to be wetted and to explain their interaction with the cementitious matrix.
