Strain Hardening Cementitious Composite (SHCC) is an innovative type of fibrereinforced
cement-based composite that has superior tensile properties. Because
of this, it holds the potential to enhance the shear capacity of reinforced concrete
(RC) beams, if applied properly. This paper presents the general and distinctive
properties of SHCC as well as a literature review of topics related to the contribution
of SHCC layers to the shear resistance of RC beams with and without shear
reinforcement. Based on the analysed results, it is concluded that the main
characteristics of SHCC are its microcracking behaviour, high ductility, and
increased tensile strength (between 2 and 8 MPa) at large deformations. When used
in structural elements, SHCC develops multiple parallel cracks compared to
concentrated cracks in conventionally reinforced concrete. The biggest
disadvantage of SHCC is its significant drying shrinkage. Although showing high
variability, using SHCC as lami...nates with a thickness of 10 mm improves the shear
capacity of hybrid RC beams, but debonding of interfaces in a hybrid system occurrs
in some cases.
