“…The size, shape, and type of aggregate, the bond between binding agent and aggregate, and the bonding strength of geopolymer gel plays a significant role in developing the STS [50,51,[58][59][60]. It was reported that the binding strength of geopolymer gel is interrelated to the high level of dissolution of aluminosilicates in alkaline agent presences, leading to increased geopolymerization [52,61].…”

“…This matrix has a greater number of unreacted GWP particles due to the significant shrinkage in the matrix, causing the decline in FS in GPC. The formation of microcracks in ITZ is another essential aspect of lower strength development [56][57][58]69]. FS specimens that cured at room temperature are unable to support their weight.…”

Industrial waste such as Ground Granulated Blast-Furnace Slag (GGBS) and Granite Waste Powder (GWP) is available in huge quantities in several states of India. These ingredients have no recognized application and are usually shed in landfills. This process and these materials are sources of severe environmental pollution. This industrial waste has been utilized as a binder for geopolymers, which is our primary focus. This paper presents the investigation of the optimum percentage of granite waste powder as a binder, specifically, the effect of molar and alkaline to binder (A/B) ratio on the mechanical properties of geopolymer concrete (GPC). Additionally, this study involves the use of admixture SP-340 for better performance of workability. Current work focuses on investigating the effect of a change in molarity that results in strength development in geopolymer concrete. The limits for the present work were: GGBS partially replaced by GWP up to 30%; molar ranging from 12 to 18 with the interval of 2 M; and A/B ratio of 0.30. For 16 M of GPC, a maximum slump was observed for GWP with 60 mm compared to other molar concentration. For 16 M of GPC, a maximum compressive strength (CS) was observed for GWP with 20%, of 33.95 MPa. For 16 M of GPC, a maximum STS was observed for GWP, with 20%, of 3.15 MPa. For 16 M of GPC, a maximum FS was observed for GWP, with 20%, of 4.79 MPa. Geopolymer concrete has better strength properties than conventional concrete. GPC is $13.70 costlier than conventional concrete per cubic meter.

“…There is a close relationship among the activator's properties, Si/Al dissolution from precursors, and geopolymerization. Sethi et al [133] found a 178% improvement in compressive strength at the 7-day curing age of geopolymer concrete, where a 4 M NaOH activator was used to activate the precursor mix of 5% WG, 25% slag, and 70% fly ash. With the increasing concentration (2-12 M) of activator solution, the strength of the geopolymer increases, but beyond the optimum level (8-12 M), it showed a negative effect [130].…”

Recent research has revealed the promising potential of using waste glass (WG) as a binder or inert filler in cement and geopolymer concrete to deliver economic and environmental benefits to the construction sector. However, the outcomes obtained by different research groups are scattered and difficult to compare directly because of isolated process parameters. In this study, the roles and impacts of WG and process parameters on the performance of WG-added cement and geopolymer concrete are critically reviewed. This study reveals that the chemical and mineralogical composition, and particle size of WG, mix proportion, activation, and curing condition of concrete are the most important parameters that affect the dissolution behavior of WG and chemical reactivity between WG and other elements in concrete; consequently, these show impacts on properties of concrete and optimum WG level for various applications. These parameters are required to be optimized based on the guidelines for high pozzolanicity and less alkali–silica reactivity of WG in concrete. This review provides a critical discussion and guidelines on these parameters and the chemistry of WG in cement and geopolymer concrete for best practice and highlights the current challenges with future research directions.

“…The geopolymerization and hydration reactions may occur concurrently in the matrix when high calcium fly ash is used (Antoni et al 2016a;Li et al 2013). The high calcium fly ash used had similar calcium content with ground-granulated blastfurnace slag (GGBFS), which can be beneficial in increasing the compressive strength of the geopolymer (Sethi et al 2018). Both reactions can improve the quality of the resulting matrix.…”

AbstractGeopolymer is synthesized by mixing material rich in alumina and silica, such as fly ash, with a highly alkaline solution to form a hardened matrix. However, when using high calcium fly ash as a precursor, a flash set frequently occurs, i.e., the mixture hardens very rapidly before casting can be completed. The use of borax as an additive has been reported due to its potential to prolong the setting time. In this study, the use of a significantly higher dosage of borax is explored. The results show that the addition of borax up to 20% of fly ash, by mass, into the alkaline solution prolongs the setting time by up to 90 min. Conversely, the addition of higher amounts of borax tends to decrease the compressive strength of the geopolymer, whereas adding a small amount of calcium oxide into the mixture increases the strength marginally, especially when the borax content is small. However, the amount of calcium oxide should be limited because at higher content, the effectiveness of borax to prolong the setting time is reduced.
