“…However, J. Venkateswararao, K. Srinivasa Rao and K. Rambabu (2017) [4] used Fly ash, GGBS, and OPC in a confined ratio to study the performance of glass fiberreinforced GC. Paper sludge ash, Metakaolin, High Magnesium Nickel Slag (HMNS) can also be used for research investigation [9,15,18,22,24,35].…”

“…The carbon emissions of the cement only during the manufacturing process is 1.5 billion tonnes which is 5-7 % of the total CO 2 emission globally in a year which is recorded as the highest contribution towards environmental pollution [13,14,17]. Hence low CO 2 binding agents are abstracted from industrial by-products which are rich in silica and alumina such as Metakaolin [15,18], Fly ash [1,13,16,18], Ground Granulated Blast Furnace Slag (GGBFS) [1,15], Palm Oil Fuel Ash [26], calcinated clays, Rice Husk Ash (RHA) [31] and some natural zeolites. It is noted that the CO 2 emission is reduced by 60% in the manufacturing of geopolymer concrete [15].…”

Metakaolin (MK) is proved to be better among all other binding agents and the Metakaolin geopolymer has persisting properties.…”

Nowadays the environmental health is considered to be the most important topic for concern. The emission of CO2 and other harmful gases to the atmosphere become a serious problem and the root cause of environmental alteration. In other ways, the production of cement is reducing continuously due to the unavailability of resources and a large amount of carbon footprint. To overcome all these problems the low CO2 emitting and alumina silicate rich sources are used as binders instead of ordinary cement. The paper reviews all the recent and experimental works done by the researchers in order to study the physical and mechanical properties of Geopolymer Concrete with different mixtures of binders and additives introduced for increasing the strength and durability. The use of different industrial by-products in concrete development is encouraged and the workability, effects of temperature variation, use of admixture, fibers and effects of water- binder ratio for the Geopolymer Concrete are examined. Reviews indicate that the compressive strength of the Geopolymer Concrete with additional hooked end steel fibers are more than that of controlled Geopolymer Concrete mix.

“…However, due to the brittleness of the material, it is important not only to investigate the material properties under quasi-static loading conditions but also the responses of material at dynamic loading. In this line, it has already been shown that cementitious composites can exhibit different mechanical behavior when exposed to low-or high-velocity impact events [5][6][7][8]. Fibers have a significant role in the impact resistance of fiber-reinforced cementitious composites [9], which is influenced multiple factors such a type and shape of the fibers [10][11][12][13], fiber/matrix interaction, and distribution and orientation of the fibers [14].…”

This study evaluates the effects of the manufacturing process and fiber reinforcement on low-velocity impact response of the recently developed PVA fiber-reinforced alkali-activated stone wool composites. To this end, reinforced and unreinforced specimens manufactured by hot-pressing were compared with those oven curing. The results revealed a similar impact response for the hot-pressed composite produced at 120 ° C for 3 h and its counterpart cured at ambient pressure at 60 ° C oven for 24 h. Furthermore, fiber reinforcement significantly improves the impact resistance of the hot-pressed composites showing about a 50% increase in peak load and a 40% reduction in penetration compared to the unreinforced materials. In view of the development of the hot-pressed composites and potential applications, accurate predictive models are of extremely importance, hence the material mechanical behavior was here simulated by adopting the concrete damage plasticity model to predict the low-velocity impact response of both unreinforced and reinforced materials and successfully verified for the scaling-up purpose.

“…They can be produced with pozzolanic waste materials instead of PC, which has made UHPGPC an eco-friendly and more sustainable material than conventional UHPC. [7][8][9][10] The replacement of PC with pozzolanic waste materials in UHPGPC mixtures enables UHPGPC to have higher strength, lower permeability, and superior durability properties. However, similar to UHPC, UHPGPC are very sensitive to the effect of high temperature after a possible fire, and significant reductions in their physical, mechanical, and durability properties occur.…”

This paper primarily examines the flowability, physical appearance, mass loss, residual compressive strength (RCS), and residual flexural strength (RFS) properties of steel (ST) and basalt (BA) fiber-added sustainable ultra-high performance geopolymer cement (UHPGPC) mortars exposed to hightemperature effects. According to the results obtained, ST and BA fibers adversely influence the workability properties of UHPGPC mortars and thus significantly reduce the spreading diameters of the mortars. However, ST and BA fibers substantially improve the RCS and RFS capacities of UHPGPC specimens exposed to high temperatures because they have a powerful bonding effect with the matrix and effectually restrict the development of micro-and macro-cracks with their bridging effect. Furthermore, this phenomenon is slightly more effective in hybrid form than using ST and BA fibers.
