Title: Development and analysis of high performance hybrid cement composites
Author(s): V. J. FERRARI, J. B. DE HANAI
Appears on pages(s): 254-261
Keywords: cementitious composites, hybridization, flexional tougheness, fracture toughness.
Abstract:In this work, the hybridization effect in cimentitious composites is studied in an attempt to modify the material and to improve the process of transference of stress of the matrix to steel fibers. Steel short fibers and steel microfibers were used in a mortar matrix for production of notched beams of 150 mm x 150 mm cross section with a length of 500 mm. Tests in beams under three point loading were conducted with crack mouth opening displacement (CMOD) control. The performance of the hybrid composites were compared with the performances of steel short fibre composites and matrix. The results were analised considering the flexional toughness and fracture tougheness parameters. The hybridization process have shown to have a satisfactory behavior translated for a strain hardening.
