“…Recently, the strength properties of GPC with RHA, FA, GGBS, and nano TiO2 (NT) were studied and obtained the maximum strength of 16 % increase with RHA (10%) and TiO2 (4%) incorporated GPC specimens [50]. Although, 20% of RHA addition produced maximum strength with MK (20%), FA (30%), and GGBS (30%), but further addition of the RHA reduced GPC strength [27]. GPC developed from FA, nano-clay (NC), and NT enhanced strength at 1% of NC and 1.25% of NT.…”

“…RHA utilization in concrete is the best solution for waste disposal and reduce carbon dioxide emissions. It gives better strength due to high amorphous silica content, high surface area, and porous structure [25][26][27][28]. Generally, FA blends with similar high-silica sources materials like GGBS, Silica fume, RHA, and Nano silica to form a suitable chemical composition of geopolymers [29].…”

In this study, Geopolymer concrete (GPC) blended with fly ash (FA), ground granulated blast furnace slag (GGBS), rice husk ash (RHA), and nano-silica (NS) developed and investigated in three aspects: In the first aspect of GPC (FA+GGBS), FA varied from 0-100% of GGBS at 10 % intervals to determine the optimum proportion of FA-GGBS. In the second aspect of GPC (FA+GGBS+RHA), RHA varied from 0-25% of FA at 5% intervals with a constant of 30% GGBS attained from the first aspect of the study. In the third aspect of GPC (FA+GGBS+RHA+NS), NS was replaced with 1, 3, and 5% with the optimum proportions of GGBS (30%) and RHA (15%) obtained from the first and second aspects of the study. The fresh and hardened properties of GPC were obtained at 7 and 28 days under ambient curing. The compressive strength improved while FA was replaced by GGBS (0-100%) from 27.75 to 45 MPa. Meanwhile, workability has decreased to 0.81 from 0.97. Hence, the optimized proportion of FA and GGBS was obtained as 70:30 from the workability aspect. RHA replacement provided compressive strength increment up to 15% (39.5 MPa), but workability gradually decreased (0.92 to 0.84) from 0 to 25%. So, the optimum proportion of RHA was achieved by 15% from the second aspect. In the third aspect, the workability increased from 0.89 to 0.92 while NS replacement (0-3%) with FA. Also, compressive strength has improved from 39.52 to 41.95 MPa. Thus, the optimized NS proportion gained at 3% of NS. Overall, this study provides a view of industrial by-product utilization as part of GPC in optimal proportions.

“…In order for concrete constructions to be long-lasting, it is necessary to ensure that they are compacted adequately and appropriately. The topics of global warming and regular climate fluctuations are currently prominent worldwide [10,11]. The growing demand for cement production and its use in concrete is linked to environmental pollution and the significant release of greenhouse gases [12,13].…”

This research paper explained in detail how well regular concrete works and how well concrete with fly ash and ground granulated blast furnace slag (GGBS) performs as a substitute for cement. Through a series of experiments, the objective of the study was to perform an experiment that promotes the usage of partial replacement-based concrete which can replace the conventional concrete as well as contributes to sustainable development. A dedicated methodology was developed for the study, focusing on the mechanical and durability properties of the materials with inducing sustainable materials. The methodology study examined the mechanical properties, durability, and microstructural attributes of concrete blends. Cement concrete specimens with binder ratios (%) of 0.3, 0.4, and 0.5 were tested for compressive strength, rapid chloride permeability, SEM, and XRD at 28, 56, and 90 days. Fly ash and GGBS were used to partially replace cement at 0% to 70% for all binder ratios by weight of cement. There were optimal replacement percentages for each binder ratio and fly ash; the concrete partially substituted with GGBS had similar or enhanced mechanical properties to conventional concrete. The novelty of the study is to incorporate microstructure analysis for the same samples that shall enable analysing the behaviour of the partial replaced materials with conventional concrete. In connection with the results, the study had found lower RCPT values in partial replacement concrete specimens, fly ash and GGBS increased chloride ion resistance. SEM and XRD analyses revealed the microstructural properties and phase composition of concrete mixtures, showing how supplementary cementitious materials refine pore structure and provide durable hydration products. This study shows that fly ash and GGBS can improve concrete performance as well as reduce impact on environment and applications in construction.

“…The use of granite slurry powder enhances the performance of GPC. Ternary geopolymer concrete, which is a combination of three materials, showed superior performance in comparison to both binary geopolymer concrete, which is a blend of two materials, and quaternary geopolymer concrete, which is a blend of four materials [11,12]. Along with GSP, Glass Powder is also exhibiting greater strength in geopolymer because of it contain high dosage of silica by using this we can reduce the disposal problems of glass powder which is derived from glass industries [13,14].…”

Geopolymer concrete, with its high compressive strength and low permeability, is ideal for sturdiness and environmental resistance in construction projects. It can lower greenhouse gas emissions compared to conventional concrete. India has abundant quantities of effluent from factories, namely Glass powder (GP), Ground granulated blast furnace slag (GGBS), and Granite slurry powder (GSP). The GSP is an environmentally friendly substance that has no recognized applications, is usually disposed of in landfills, and pollutes the air and creates infiltration issues in nearby communities. The mechanical characteristics of geopolymer concrete (GPC) with different ratios of GSP, GGBS, and glass powder were the main focus of this investigation. Moreover, finalized the optimum mix from strength criteria and studied the durability properties by maintaining a constant molarity of 16M in ambient curing. Initially five mixes (G0-50, G50-0, G25-25, G30-20, G20-30) were prepared and determined their compressive strengths based on that identified an optimum mix G-30-20. Optimum mix was prepared with 50% GGBS, 30% GSP, and 20% GP as binder content. The compressive, splitting tensile, flexural and bond strengths at the age of 28 days of optimum mix was 91 MPa, 4.72 MPa, 6.96 MPa and 10.08 MPa respectively. Furthermore, observed a very low rate of water absorption of 0.28%, sorptivity 0.4 mm/ s . and UPV value is 4.8 km/s, it indicates geopolymer concrete has superior quality. Based on the results obtained from several mix proportions, the combination of 30% GSP, 20% GP, and 50% GGBS can be used as a sustainable concrete, which offers better results in durability and mechanical properties.
