“…The increase in fiber content also increased the possibility of fiber agglomeration and fiber blockage at the reinforcement of the L‐shaped box, thereby reducing the passing capacity. Similarly, Athiyamaan et al 34 and Rambo et al 35 observed that the L‐box height ratio decreased at increasing fiber content.…”

“…Khaloo et al 22 reported that the splitting tensile strength of medium‐strength and high‐strength SCC with 2% by volume steel fibers was increased by 20% and 10%, respectively, compared to plain SCC. Other studies 23,34 also showed that increasing the fiber content caused an increase in the splitting tensile strength of SCC. This is because the number of fibers that cross a crack increased with increasing fiber content, and the bridging action of fibers was enhanced.…”

This paper discusses the synergetic effect of ground granulated blast‐furnace slag and hooked‐end steel fibers on the fresh, mechanical, and microstructural properties of steel fiber‐reinforced self‐compacting concrete containing fly ash. A total of 12 mixtures were prepared. Hooked‐end steel fibers at four different volume fractions (0%, 0.3%, 0.6%, and 0.9%) were applied as reinforcement, while the slag contents (0%, 10%, and 30% of the cement weight) was varied; the fly ash content (20% of the cement weight) was kept constant to partially replace Portland cement. The properties of plain and steel fiber reinforced self‐compacting concrete mixtures were tested and compared. The experimental results showed that substituting cement with 10% slag effectively enhanced the workability of the fresh concrete, while replacing cement by 30% slag reduced the passing ability and filling ability. The addition of fibers reduced the workability of self‐compacting concrete. Furthermore, the addition of slag can compensate the effect on the fresh properties caused by fibers. With respect to the mechanical properties, the synergistic effect of slag and hooked‐end steel fibers improved the compressive strength, tensile strength and flexural strength. At the microstructural level, blast‐furnace slag can enhance the bonding performance of the fiber‐matrix interface, thereby improving the mechanical properties.

“…Simultaneously, the compressive and flexural strength were increased up to 3% and 5%, respectively, at the 3% optimum addition of steel fibre. Athiyamaan & Ganesh [17] also analysed the flexural performance of SCC by utilising steel fibre as a filler. In contrast, fly ash and nano-silica were partially replaced with cement.…”

Many researchers have investigated alternative sources to overcome the problem of conventional building material polluting the environment by the development of green self-compacting concrete in the construction industry. The best alternative solution is to utilise non-conventional construction materials like agricultural wastes. Meanwhile, self-compacting concrete (SCC) is considered as high strength as well as high-performance concrete. The demerits, which include tensile and flexural strength, can be improved by incorporating coir fibres. The utilisation of coir fibres also modifies self-compacting concrete performance after cracking and improves the toughness. This study defines an experimental investigation of the mechanical properties of self-compacting concrete containing coir fibres (CF) with different percentages being 0%, 0.2%, 0.5%, 1%, and 1.5% at 7- and 28-days water curing. The mechanical properties include the slump flow and compressive and tensile strength were examined. The outcomes demonstrated that a required slump flow for self-compacting concrete was achieved using coir fibres up to 1%, beyond which it reduced the slump significantly. The length of fibre and proportion of fibres directly affected the workability. The compressive strength was 10% to 15% enhanced with the incorporation of coir fibres up to 0.5%; after that, the strength was slightly reduced, and tensile strength was 30% to 50% improved compared to conventional self-compacting concrete up to 1% of coir fibres incorporation in the SCC mix, after which it rapidly reduced.

“…Regarding the effect of mineral admixtures on the properties of fiber-reinforced cement paste, mortar or concrete, in a rheological study, concrete mixtures with mineral admixtures have better fresh concrete properties. Steel fibers increase the flexural strength of concrete and prevent it from brittle failure [ 40 ]. In the study of the effect of mineral admixtures on the properties of ultra-high performance fiber-reinforced concrete in the fresh state, it was found that due to factors such as the difference in particle shape and the strength of inter-particle bonds, the addition of metakaolin and silica fume on the plastic viscosity of fresh mixtures will have different effects.…”

The use of a high volume of industrial solid waste mineral admixture and hybrid fiber can greatly reduce the amount of cement in mortar or concrete, improve its performance, ensure the service properties of mortar or concrete, and reuse industrial solid waste to reduce the environmental burden, which has significant research significance. In this paper, the mechanical properties, wear resistance and microstructure of hybrid fiber-reinforced mortar (HFRM) with a high content of industrial solid waste mineral admixture were systematically studied under different water/binder ratios. Mineral admixtures include fly ash, silica fume and granulated blast furnace slag (slag). The total content of hybrid glass fiber (GF) and polypropylene fiber (PPF) was 2% by volume fractions, and six different water/binder ratios ranging from 0.27 to 0.62 were used. The following conclusions were drawn: fibers have a significant negative effect on the properties of mortars with a low water/binder ratio (w/b = 0.27) and high content of mineral admixtures. In general, the effect of adding hybrid fiber on improving the wear resistance of mortar is more obvious. The average residual weight of hybrid fiber-reinforced mortar is the highest after the wear resistance test. Comprehensively considering the compressive strength, flexural strength, wear resistance and microstructure of the mortar samples, G8PP2-0.40 is the optimal mix ratio. At this time, the replacement rates of fly ash, silica fume and slag are: 20%, 5% and 30%, the water/binder ratio is 0.40, and the content of GF and PPF is 1.6% and 0.4%, respectively.
