“…In general, higher fibre volume in the mix result in an increment in the residual flexural strength, flexural toughness, energy absorption as well as the load bearing capacity due to improved ductility of the material. Inclusion of steel fibres enhances the ductility and the splitting tensile strength of SCC by the fibre knitting between cracks that allows stress transfer at the crack openings [13], [16].…”

“…It has been widely used especially for on ground applications such as industrial pavements, roads, parking areas as well as for airport runways [11] considering the advantages in enhancing the durability against cracking and the strength of the structure at early ages [12], [13]. Nevertheless, studies are carried out to investigate the application of steel fibres for elevated slabs, functioning as crack resistor as well as replacement of reinforcements to accommodate loadings and shears.…”

“…However, for slabs that utilizes steel fibres as the only reinforcement to resist flexural loading and shears, at least 1% volume fraction of fibres is required [13], [15], [16], [19], [20]. Higher amount of steel fibres also increases the energy absorption capacity of the concrete mix [13] and develop higher post crack residual tensile strength that results in a more significant load carrying capacity that exceeds the cracking load [23].…”

“…SFRSCC combines the benefits of SCC at fresh state with high workability as well as its improvement of the properties at hardened state with addition of the steel fibres [7]. Steel fibres has the ability to improve the properties of SCC elements including tensile strength, ductility, toughness, energy absorption capacity [8], [9], fracture toughness [1], [10], [11] as well as cracking resistance [12]. Owing to the positive effects of steel fibres in enhancing the concrete materials properties especially by its contribution against crack propagation and enhancement in ductility, current research is now moving towards investigating the function of the fibres as the reinforcing material to partially or totally replace conventional reinforcements in concrete structures [13].…”

Abstract. This paper investigates the effects of steel fibres as a replacement to the conventional reinforcement under flexural behaviour and punching shear in self-compacting (SCC) ribbed slab reinforced with steel fibres. Four ribbed slabs with similar dimensions of 2.8 m length x 1.2 m width and 0.2m thickness were constructed. Two of the samples were considered as control samples (conventionally reinforced with reinforcement bars and welded mesh) while another two samples were fully reinforced with 1% (80 kg/m 3 ) volume of steel fibres incorporated to the SCC mix. For the flexural behaviour study, the ribbed slab samples were subjected to two line loads under four point bending. Meanwhile, for the punching shear analysis, the ribbed slab samples were subjected to a point load to simulate loading from the column. The analysis of the experimental results displayed that steel fibres incorporation had been found to effectively delay the first crack occurrence under both flexural and punching shear. The steel fibre replacement has been proven to be able to sustain up to 80% and 73% of the ultimate load resistance for flexural and punching shear, respectively, in comparison to conventionally reinforced ribbed slab structure. The visual observation carried out during the experiment exhibited similar failure mode for both steel fibre reinforced and control samples. This was observed for both flexural and punching shear samples. Overall, it can be concluded that the steel fibres had displayed a promising potential to effectively replace the conventional reinforcements.

Geopolymer concrete (GPC) is an innovative construction material that shows great potential. Not only is it environmentally friendly in its manufacturing process, but it also has a minimal carbon footprint. By reducing CO2 emissions and offering a long‐term solution to the depletion of natural resources, GPC presents itself as a promising option. In this study, ambient cured GPC was prepared using ground granulated blast furnace slag (GGBS), NaOH, Na2SiO3, manufactured sand, and natural coarse aggregates. Additionally, Metakaolin and Nano‐silica were incorporated into the mix at volume fractions of 10%, 20%, 30%, and 40%. Nano‐silica 0.5% and 1% respectively. To assess the practicality of these elements in structural applications, Reinforced Concrete (RC) slabs were casted and their flexural behavior was studied. Experimental evaluations were conducted under four‐point bending conditions. Furthermore, a Finite Element Analysis (FEA) was performed using the ANSYS APDL tool to compare the experimental results. It is evident from the findings that SL2 (Metakaolin 30% + Nano‐silica 0.5%) exhibited superior properties compared to SL1 (Metakaolin 30%) in all aspects. This research showcases how GPC can be optimized for enhanced structural performance and contributes toward sustainable construction practices.
