Abstract:
The construction industry is in need of finding cost effective materials for increasing the strength
of concrete structures. Slurry infiltrated fibrous concrete (SIFCON) is one of the recently
developed construction materials that can be considered as a special type of high-performance
fiber reinforced concrete (HPFRC) with higher fiber content. An endeavor has been made in the
present investigations to study the influence of addition of locally available material at different
dosages to the total weight of concrete. An experimental program was carried out to investigate
the compressive strength, flexural strength, Non-Destructive Test (NDT), such as rebound
hammer test and ultra-sonic pulse velocity test, and durability test such as sulfate attack. The
investigations were done using cement-based mix and tests were carried out as per recommended
procedures by appropriate codes. SIFCON specimens with 0%, 5%, 10% and 15% volume of
fraction fibers and with aspect ratio (L/D) 20, 25 and 30 were used in this study. Test results
were presented in comparison of SIFCON with conventional plain concrete. The load carrying
capacity of SIFCON specimen is found to be higher than conventional plain concrete and it also
reduced crack width. SIFCON was found to have many differences from conventional plain
concrete and fiber reinforced concrete. Regarding its mix constitute material, fresh SIFCON
properties and hard SIFCON properties. Therefore, special standard test methods and compliance
criteria should be prepared for this material.
