“…Geopolymer concrete (GPC) offers a promising solution by eliminating the need for Portland cement as a binder. Instead, supplementary cementitious materials like fly ash, ground granulated blast furnace slag (GGBFS), rice husk ash (RHA), silica fume (SF), and metakaolin are utilized [2]. These materials, rich in silicon (Si) and aluminum (Al), are activated by alkaline liquids such as sodium hydroxide (NaOH) and sodium silicate (Na2SiO3) to form the geopolymer binder.…”

Self-Compacting Geopolymer Concrete (SCGC) emerges as a groundbreaking construction material in the domain of concrete technology. This method integrates supplementary cementitious materials (SCM), alkaline solutions like sodium hydroxide and sodium silicate, and a superplasticizer to form a binder for matrix development and strength enhancement, thereby eliminating the need for compaction.In the present study, fly ash-based Self- Compacting Geopolymer Concrete (SCGC) was substituted with varying proportions of Ground Granulated Blast Furnace Slag (GGBS). Concrete specimens were subjected to curing under both oven and ambient conditions to assess their performance.The investigation unveiled that incorporating GGBS into fly ash-based SCGC resulted in reduced workability alongside improved strength with increasing binder content. Notably, SCGC samples cured at 70°C for 24 hours with a 50% replacement of GGBS emerged as the optimal proportion, meeting the required workability standards. However, surpassing this threshold led to a further enhancement in mechanical properties albeit at the expense of reduced workability.

“…[8,9]. Geopolymers prepared from low calcium types like low calcium fly ash yield fair engineering properties, better temperature properties, and reduced drying shrinkage and creep [10][11][12]. Geopolymer concrete needs high curing temperatures ranging from 80oC to 120oC for a duration of 4 to 20 hours [12,13].…”

Applications of geopolymer concrete are increasing at a faster rate globally and are actively replacing cement concrete in all its facets. Regarding this, the advancement of, self-compacting geopolymer concrete is inevitable. The present study deals with the investigation of the effect of the molarity of sodium hydroxide solution that is to be used as part of an alkaline solution, over self-compacting and hardened properties of geopolymer concrete. Ground granulated Blast Furnace Slag (GGBS) is used as precursor material; hence, ambient curing is adopted. The alkaline activator solution is a combination of silicate solution and hydroxide based on sodium. In this work, the hydroxide solution’s molarity is varied to 8, 10, 12, 14, 16, and 18. Self-compacting properties are investigated through spread flow, T-50, V-funnel test, and L-box. The compressive strength of the hardened concrete is investigated over 7 and 28 days. Further water absorption test was also assessed in this investigation to determine the basic durability. All the specimens with different molarities exhibited fair self-compacting properties. Further optimum molarity required for the synthesis of self-compacting geopolymer concrete with fair compressive strength and excellent reduced water absorption capability is determined. The findings of this work tend to augment significant contributions to the geopolymer concrete in the facets of self-compacting nature.

“…With a higher super plasticizer dosage, the discharge duration is shortened from 11 to 8 s [7]. The flow ability (650 mm) is improved by employing 5% super plasticizer in fly ash-based SCC, according to the results reported by K. Mukilan et al [8]. Concrete mixes become more compact with the addition of significant amounts of fine aggregate, which gives excellent flow ability to self-compacting concrete [9].…”

The compressive behavior of self-consolidating concrete columns strengthened by hybrid confinement of polypropylene fiber rope and glass fiber-reinforced polymer sheet was investigated experimentally. We cast and tested eight column specimens under axial compression load. (Six confined SCC columns and two conventional SCC columns.) The concrete grade utilized is SCC M40. For reinforcement, the SCC columns are enclosed with GFRP wrap and polypropylene fiber rope in various volumetric ratios. The compressive resistance of a confined SCC column, strength enhancement, stress-strain relationship, ductility ratio, and load deflection relationship are the parameters studied. The results are compared to establish the adequacy of the confinement. The wrapping of GFRP increases the load-carrying capacity and modulus of elasticity.
