Experimental Research on Uniaxial Tensile Properties of Expanded Steel Mesh with High Performance Cement Composite Mortar
Expanded Steel Mesh(ESM)can improve the mechanical properties of High-Performance Ce-ment 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 atta-ched 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.
