Resumen
[EN] The higher paste volume in Self Compacting Concrete (SCC) makes it susceptible to have a higher creep coefficient
and cracking and has brittle nature. This brittle nature of concrete is unacceptable for any construction industry. The
addition of fibers is one of the most prevalent methods to enhance the ductile and tensile behavior of concrete. Fibers
reduce the cracking phenomena and improve the energy absorption capacity of the structure. Conversely, the addition
of fibers has a negative impact on the workability of fresh concrete. In this research work, a detailed investigation of
the influence of Nylon fibers (NFs) on fresh properties, durability, and mechanical properties of SCC was carried out.
NFs were added into concrete mixes in a proportion of 0.5%, 1%, 1.5%, and 2% by weight of cement to achieve the
research objectives. Durability assessment of modified SCC having Nylon fibers was performed using water absorption,
permeability, carbonation resistance, and acid attack resistant. Mechanical tests (compressive and tensile) were conducted
for modified as well as control mix. Test results indicate that the passing and filling ability decreased while segregation
and bleeding resistance increased with NFs. Furthermore, test results showed a significant increase in strength up to
1.5% addition of nylon fibers and then strength decreases gradually. Durability parameters were significantly improved
with the incorporation of NFs relative to the control mix. Overall, this study demonstrated the potential of using nylon
fibers in self-compacting concrete with improved durability and mechanical properties.
