마이크로 역학에 의하여 설계된 고인성 섬유복합 모르타르의 1축인장 거동

Abstract

A high ductile fiber reinforced mortar has been developed by employing micromechanics-based design procedure. Micromechanical analysis was initially performed to properly select water-cement ratio, and then optimal mixture proportion was determined based on workability considerations, including desirable fiber dispersion without segregation. Subsequent direct tensile tests revealed that the fiber reinforced mortar exhibited high ductile uniaxial tension property, represented by strain capacity, which is around 100 times the strain capacity of normal concrete.
