“…The flexural strength for samples with 1% addition of fibers was 9 MPa and for samples without reinforcement and with 0.5% fibers addition it was below 7.2 MPa [78]. Recently also the hybrid composition included PP and glass fibers [79] and compositions with PP and PO fibers are investigated [80].…”

“…The next research challenge is also the optimization of the production process of these materials. In this aspect, it is worth mentioning the elimination of the curing at high temperatures and the possibility of developing geopolymer materials hardened at ambient temperature [23,29,79,81,[83][84][85]. Such research works are undertaken in some research centers, but they do not always allow obtaining materials with satisfactory mechanical properties [29,44].…”

“…Such research works are undertaken in some research centers, but they do not always allow obtaining materials with satisfactory mechanical properties [29,44]. Such work is currently carried out for composites with polymer fibers and brings much better results than for a plain matrix [79,81,[83][84][85]. The second solution that allows the price of materials to be reduced, and at the same time the safety of their production to be improved, is to replace the alkaline compounds used in the geopolymerization process with acids.…”

The article describes the state of the art in reinforced geopolymers, taking into consideration various types of polymer fiber reinforcements, such as polypropylene, polyethylene, or polylactic acid. The description is focused on the usage of polymer short fibers and the mechanical properties of the geopolymer composites. However, to show a wider research background, numerous references are discussed concerning the selected studies on reinforcing geopolymer composites with long fibers and fabrics. The research method applied in the article is the critical analysis of literature sources, including a comparison of new material with other materials used in similar applications. The results of the research are discussed in a comparative context and the properties of the composites are juxtaposed with the properties of the standard materials used in the construction industry. Potential applications in the construction industry are presented. Moreover, the contemporary research challenges for geopolymer materials reinforced with fibers are presented.

“…Many GPCs are currently generated with growing concentrations of Al 2 O 3 and SiO 2 , which improve the phase of geopolymerization and the amount of GPC [sodium aluminosilicate hydrate (NASH), calcium aluminosilicate hydrate (CASH), and calcium silicate hydrate (CSH)] gel. These also contributed to an improvement in the strength of the GPC (Dombrowski et al 2007;Husein et al 2016;Chithambar Ganesh & Muthukannan 2019a;Arunkumar et al 2020Arunkumar et al , 2021. CSH and CASH are produced in the hydration process of Portland cement.…”

Incinerated Bio-Medical Waste Ash (IBWA) is toxic waste material with broad potential (cancer, genetic risk, premature death, permanent disease) to inflict severe health damage for the atmosphere and humans. This waste is disposed of as landfills which contaminate the underground water and environment. The effective way of disposal of IBWA is by utilizing it as a building material which can reduce the hazardous toxic materials. The use of Geopolymer Concrete (GPC) combined with IBWA as a substitute for Ground Granulated Blast Furnace Slag (GGBS) has been researched for its ability to create a new type of Green Concrete. The physical and chemical properties were observed for the raw materials. IBWA was used at 0, 5, 10, 15, 20, 25, 30, 35, 40, 45 and 50% replacement by weight for GGBS. Mixing proportions were 1:2.21:3.48 respectively for GGBS, Manufacturing Sand (M-sand), and coarse aggregate. Fresh properties and Mechanical properties were examined on all specimens. The findings show an increase in the setting time and flow of concrete and a decrease in density with improved utilization of IBWA. On the other hand, IBWA replacement for GGBS enhanced the mechanical properties. These results revealed that IBWA could be partially replaced as source material for Geopolymer Concrete. This research may contribute to the reduction of dangerous IBWA as a building material.

“…There was a research gap on utilizing the rubber as a fibre with a smaller volume fraction in this study. Further, a combination of both PP and rubber fibre could allow enhancing the properties of GPC in all aspects to use in heavy-loaded structural elements [44].…”
