This study was aimed to investigate the tensile behaviors of PE fiber-reinforced highly ductile cementitious composites with different combinations of micro silica sand and normal sand with maximum particle size of 4.75mm. This study presented the feasibility of using normal sand instead of micro silica sand for highly ductile cementitious composites with equivalent or better uniaxial tensile performance.
