The ultimate tensile strain of SECCs was 0.38–2.40%, the ultimate tensile stress of SECCs was 2.56–4.58 MPa, and the compressive strength of SECCs was 37.81–64.66 MPa. The content of fly ash and sea sand had a highly significant positive effect on ultimate tensile strain.

Summary of short- and long-term tensile properties of FSS-ECC and GPA-ECC: (a) tensile strength, (b) tensile strain capacity, and (c) strain energy density. From the stress-strain curves, the tensile strength of GPA-ECC was found to be lower than that of FSS-ECC probably because the use of large GPA size (2.36–4.75 mm) negatively …

They discovered that the tensile strength difference between the two

the usage (%) of SD in concrete without compromising the strength of concrete ﬁber reinforcement can be a good solution. Fiber reinforced concrete (FRC) is becoming popular due to its promising performance in structural reliability (Verma, 2016). Fiber improves ﬂexural strength, splitting tensile strength, freeze-thaw resis-

The stability of reinforced concrete structures mainly depends on the mechanical properties of concrete, i.e., its compressive strength f c and tensile strength f t. Different kinds of inexpensive cement replacement materials (CRM) can be used to form hybrid concrete (HC) with enhanced mechanical and other properties.
