Performance Research of Strain Hardening Cementitious Composites (SHCC) under Uniaxial Tensile Load

Abstract:

Strain Hardening Cementitious Composites (SHCC) varied with mixture proportion was preparated with normal engineering materials in our area, tensile performance of dumbbell specimens under uniaxial tensile load was experimentally investigated in this paper, and tensile stress versus strain curves as well as crack development of SHCC with different mixture proportion were obtained. The results showed that all specimens had strain-hardening and multiple-cracking characteristics obviously, among them, ultimate tensile strain of No.A and C series could exceed 3%. SHCC with excellent stable tensile performance was preparated based on normal river sand but not quartz sand, which can reduce project cost and promote the application and development of SHCC in practical engineering.
