“…However, for passing ability and filling ability, the test results exceeded the limits, even for M4 specimens. It was observed that the fresh properties could be enhanced by increasing the percentage of superplasticizer, same has been reported in previous studies also [21][22][23][24][25][26]. 5 presents the mechanical properties of GGBS-based SCGC specimens.…”

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.

“…The compressive strength decreased by 32.95%, 15.71%, 15.05%, 19.61%, 28.48%, and 31.00% in the SCC blends containing 0%, 10%, 20%, 30%, 40%, and 50% of CSA as the acid concentration-time rose from 28 to 120 days. This decrease in the concrete strength is due to the OPC's ability to absorb more hydrochloric acid being enhanced by a high calcium carbonate (CaCO 3 ) concentration [75,77]. The fineness of the cement boosts the acid's aggressiveness, allowing it to quickly leach the paste, especially on the bare surface of the specimen.…”

Recycling trash and protecting natural resources are two of the many benefits of using copper slag as a fine aggregate in a concrete building. However, stakeholders need proven research output to build trust and initiate or enhance the use of such industrial waste in buildings. This study evaluated self-compacting concrete’s fresh and hardened characteristics (SCC) comprising a copper slag aggregate (CSA). For this purpose, six mixes were prepared by substituting river sand with CSA up to 50%, with a 10% increment. The properties of fresh SCC were evaluated using slump flow, V-funnel, and L-box tests. Several parameters of SCC were examined, including water absorption, sorptivity, chloride ion penetration, sulphate attack, and acid attack tests. Energy dispersive spectroscopy (EDS) and scanning electron microscopy (SEM) were used to investigate the concrete microstructure. The results indicated that the fresh characteristics of SCC were enhanced as the amount of CSA increased consistently. The durability properties showed a considerable enhancement in SCC mixes comprising up to 20% of CSA.

“…The focus has been made on extracting steel fibers with high strength from used tires as a concept of resource recovery from waste, reducing the need for using high-strength manufactured commercial steel fibers. Pyrolysis methods, cryogenic methods, or mechanical methods are generally employed for the recovery of rubber and steel fibers from scrap tires [8,9]. Steel fibers extracted from used tires may not have a straight or definite aspect ratio, unlike manufactured commercial steel fibers.…”

Slurry Infiltrated Fibrous Concrete (SIFCON), a modified version of Fiber Reinforced Concrete (FRC), addresses the challenge of increased fiber volume fractions. Commercially produced steel fibers are typically used in FRC and SIFCON. Efforts to reduce energy use in making commercial steel fibers have led to seeking alternative sources. Vehicular tires are typically recycled when no longer usable, yielding steel fibers among the products. Emphasis lies in recovering steel fibers from used tires as part of resource recovery from waste. Experimental work explored flexural strength in SIFCON with waste steel fibers at volumes from 4% to 7%. The study extended to assess SIFCON’s flexural strength with commercial steel fibers at similar volumes, aiming to correlate with those from waste steel fibers. M20 grade concrete and SIFCON slurry matrix specimens were cast as reference mixes for comparison. The flexural strength of SIFCON specimens with waste steel fibers recovered from used tires notably surpasses that of reference mixes and is comparable to SIFCON specimens with commercial steel fibers. Additionally, the two-layer technique proves effective in SIFCON using waste steel fibers from used tires, up to 6% volume. The test results show successful production of SIFCON from waste steel fibers recovered from used tires.
