Toughness evaluation of shotcrete reinforced with high modulus polymeric fibers

摘要

This article describes the methodology and presents results of a study of the evaluation of the post-cracking performance of shotcrete reinforced with high modulus polymeric fibers using two panel-based tests: the Plate Bending Test of EFNARC, and the Round Determinate Panel Test proposed by Bernard. A plain shotcrete and a steel fiber reinforced shotcrete have also been tested for comparison. The material properties in each case have also been characterized. An evaluation of the two panel tests has been performed considering the requirements of shotcrete applications.
