Abstract

Abstract

Expanded Steel Mesh (ESM) can improve the mechanical properties of High-Performance Cement Composite Mortar (HPCCM). Through the tensile performance tests of ESM wire nets specimens, ESM three-net specimens and ESM-HPCCM dumbbell-shaped specimens, it was found that the ESM attached to HPCCM had an obvious force effect in the long pitch direction, while the force effect in the short pitch direction was less evident. After fitting, the tensile stress-strain constitutive model of ESM mesh was established. Based on the test, the bearing capacity of ESM-HPCCM was calculated and analyzed, and the calculation method of bearing capacity of ESM-HPCCM along the long pitch direction was proposed. The ESM-steel fiber HPCCM was regarded as a whole, and the constitutional model of ESM-HPCCM material was proposed by referring to the RILEM model of steel fiber reinforced concrete.
