“…The FST achieved by FAB0C50 was 4.4 MPa which was greater than FAB50C0. The FST of GPC that had been cured at room temperature mostly followed the same growth trend as the FST of OPC concrete, according to a comparison of the engineering properties of GPC with various additives and the corresponding OPC (Jindal et al 2018 ; Nath and Sarker 2017 ; Hardjito et al 2004 ; Diaz-Loya et al 2011 ; Abbass and Singh 2021b , 2021c , 2022b ; Arora, et al 2022 ; Hadi et al 2019 ; Iftiqar Ahmed and Siddiraju 2016 ; Hamidi et al 2016 ; Dhirendra Singhal and Garg 2017 ; Abbass et al 2021 ). GPC of an equivalent grade demonstrated greater FST than OPC (Gunasekara 2016 ; Adesanya and Raheem 2009 ; Jindal et al 2018 ; Nath and Sarker 2017 ; Hardjito et al 2004 ; Diaz-Loya et al 2011 ; Abbass and Singh 2021b , 2021c , 2022b ; Arora, et al 2022 ; Hadi et al 2019 ; Iftiqar Ahmed and Siddiraju 2016 ; Hamidi et al 2016 ; Dhirendra Singhal and Garg 2017 ; Abbass et al 2021 ).…”

“…An increase in the level of sodium hydroxide from 12 to 16 M results in increased strength (Gunasekara 2016 ; Adesanya and Raheem 2009 ; Jindal et al 2018 ). The air content of the mixes depends on the shape and size of the particles in the mixes (Nath and Sarker 2017 ; Hardjito et al 2004 ; Diaz-Loya et al 2011 ; Abbass and Singh 2021b , c , 2022b ; Arora, et al 2022 ; Hadi et al 2019 ; Iftiqar Ahmed and Siddiraju 2016 ; Hamidi et al 2016 ; Dhirendra Singhal and Garg 2017 ; Abbass et al 2021 ).…”

“…The STST achieved by FAB0C50 was 4.4 MPa which was greater than FAB50C0. The CST and STST were previously reported to have increased as a result of the manufacturing of GPC using high silica and calcium-based components (Nath and Sarker 2017 ; Hardjito et al 2004 ; Diaz-Loya et al 2011 ; Abbass and Singh 2021b , c , 2022b ; Arora, et al 2022 ; Hadi et al 2019 ; Iftiqar Ahmed and Siddiraju 2016 ; Hamidi et al 2016 ; Dhirendra Singhal and Garg 2017 ; Abbass et al 2021 ).…”

In this study, geopolymer concrete (GPC) is prepared using fly ash as source material along with alkaline activators (sodium hydroxide + sodium silicate) for sustainable development. There are three different sodium hydroxide molarities: 8, 12, and 16 utilised. Incinerated biomedical waste ash (BMW) and bone China waste (BCW) are substituted for the fine aggregates in GPC at varying ratios of 10, 20, 30, 40, and 50%. The utilisation of wastes in place of fine aggregates in GPC are helpful in solving the dumping problem of wastes, saving energy, and natural resources (sand quarries). The results showed that, relative to the control mix, the density, workability, and strength increased up to 60% replacement of sand by 30% BMW and 30% BCW and beyond this, the strength and other properties decreased. In contrast to the combination of 50% BMW and 0% BCW, the mix with 50% BCW and 0% BMW demonstrated great strength. In terms of molarity, the mixes with 16 M sodium hydroxide concentration showed higher workability, density, strength and lower air content as compared to the mixes with 8 M and 12 M sodium hydroxide concentration.

“…Basalt fibers are widely used in the production of fiber-reinforced concrete due to their low cost, simple production process, and high elastic modulus [ 34 , 35 ]. Mahapara et al [ 36 ] concluded that the mechanical strength of basalt fiber-reinforced concrete increased by 88%, 89%, and 92% at 7 days, 28 days, and 90 days, respectively. Abbass et al [ 36 ] found that concrete with an appropriate basalt fiber content could reduce the weight loss rate through acid corrosion by 27.43%, and the penetration depth of chloride ions was 2 mm.…”

The aim of this study was to investigate the properties of fiber-reinforced pervious concrete. Ordinary cement, silica fume, coarse aggregate, and basalt fibers were used to produce the concrete mix. The fibers were mixed with pervious concrete at the levels of 0 kg/m3, 2 kg/m3, 4 kg/m3, 6 kg/m3, and 8 kg/m3 to the investigate their influence on the mechanical and physical properties of pervious concrete. It could be observed that the cubic compressive strength, axial compressive strength, and flexural strength increased and then decreased as the content of basalt fiber increased, while the permeability and porosity of the pervious concrete decreased with the increase in the basalt fiber content. The mesostructure of pervious concrete was also studied through industrial computed tomography (ICT); the testing phenomenon showed that the fibers had a significant influence on the arrangement of the aggregate, cement paste, and the interfacial transition zone, and excessive basalt fiber resulted in poor characteristics of the interfacial transition zone (ITZ) and inferior strength properties. It was found that incorporating a basalt fiber content of 4 kg/m3 could achieve a balance between the mechanical and physical properties of pervious concrete, which was suitable for structural applications.

As an environmentally friendly building material, recycled pervious concrete can not only alleviate the increasingly severe urban flooding and heat island effect, but also realize the resource utilization of construction waste. However, the porous nature of recycled pervious concrete leads to its low strength, and there is an urgent need to develop recycled pervious concrete with good mechanical and permeability properties. This paper proposes to mix fly ash and basalt fibers in the waste brick aggregate pervious concrete, and investigate the effects of mixing fly ash and basalt fibers on the properties of recycled brick pervious concrete by comparing the mechanical properties, water permeability and frost resistance of recycled brick pervious concrete. The results show that: with the increase of fiber admixture, the mechanical properties and frost resistance of recycled brick-mixed permeable concrete are improved, and the water permeability is decreased; fly ash is more obvious to improve the late strength of recycled brick-mixed permeable concrete, with the increase of fly ash admixture, the mechanical properties and frost resistance of recycled permeable concrete are improved, and the water permeability is decreased, and the excessive admixture of fly ash will greatly reduce the water permeability of recycled brick-mixed permeable concrete. Excessive incorporation of fly ash will greatly reduce the water permeability of recycled pervious concrete. Under the premise of better water permeability and mechanical properties, the optimal mix combination of 10% fly ash and 0.05% basalt fiber was selected on the basis of 85% recycled concrete aggregate and 15% brick aggregate as the mixed coarse aggregate.
