“…The inclusion of 10% alccofine as a replacement to the slag cement enhanced the compressive strength of RAC by 11%. This is due to the finer particle size and due to the formation of additional C-S-H gel, which is formed due to the reaction of Ca(OH) 2 with alccofine, which was also concluded by S. C. Boobalan, et al [28] in their study.…”

The demand for sustainable construction materials has driven the exploration of various innovative approaches to enhance the properties of concrete for reducing its environmental impact. The present study examines the effects of incorporating recycled concrete aggregate (RCA), slag cement, alccofine, and glass fibers into concrete mixtures. In the present study, it has been observed that recycled concrete aggregate (RCA) exhibits inferior properties, including higher water absorption and poorer performance, when compared to natural coarse aggregate. Various replacement levels of RCA were utilized in this study to assess its impact on concrete performance. Alccofine, a supplementary cementitious material, is used to partially replace the binding material. Additionally, glass fibers were added to enhance the flexural and tensile behavior of the concrete. The concrete mixtures were designed to meet the required strength and durability specifications. A comprehensive testing program was conducted to evaluate the fresh and hardened properties of the concrete. A slump cone test was performed for assessing the workability of fresh concrete. For hardened concrete, compressive strength, flexural strength, and split tensile strength are evaluated. The results demonstrated that incorporating RCA, slag cement, alccofine, and glass fibers into the concrete mixtures improved mechanical properties. The use of RCA led to a reduction in natural resource consumption, namely natural coarse aggregate in concrete. On the other hand, the generated construction and demolition (C&D) waste is used effectively. Portland slag cement (PSC) and alccofine (A) improved the long-term strength of concrete. The addition of glass fibers significantly enhanced the tensile and flexural performance of the concrete, resulting in improved crack resistance and overall performance. This study introduces a novel concept by exploring the potential utilization of recycled concrete aggregate, slag cement, alccofine, and glass fibers in combination as sustainable and high-performance components in concrete mixtures. Previous research has not extensively studied this combination of materials, making it a unique and innovative approach. These findings contribute to the development of eco-friendly construction practices and provide insights for engineers, researchers, and practitioners aiming to incorporate recycled materials and supplementary cementitious materials into concrete construction.

“…Alccofine is a highly cementitious material, very finer as contrasted with normal cement particle size, and used as a partial replacement for cement, it can be used in the preparation of special types of concretes such are self-compacting concrete Kusuma Mounika et al [8] as it can enhances the workability of the concrete as well, can be employed to develop high strength concrete Bharat et al [9], and in GPC, it can be used in GPC mix as a strength enhancer mentioned by Prince Goyal et al [10] and its combination with other cementitious materials can lead concrete to attain the high early strength characteristics by the study was conducted by Boobalan et al [11], and the finer content of cementitious materials reduces the voids present in the concrete mixes that were significantly reduced by the CSH gel formed mentioned by the microscopic study given by Sagar and Shiva [12], hence the concrete becomes denser with an excellent interlocking structure G. Balaji et al [13] and it can withstand elevated temperatures given by based on the study conducted by Chandrakanth et al [14].…”

Geopolymer concrete (GPC) emerging as the most innovative construction material, which not only reduces the requirement of Ordinary Portland cement (OPC) but also enhances the properties of the concrete as well, and decreases the ejection of harmful gases into the atmosphere like Carbon dioxide (CO2), Nitrogen, and Sulphur, Which is a prime concern for the environment. The need for concrete is raising uncharacteristically and so does for the OPC, to minimize the demand for OPC cementitious materials like Fly ash, Ground Granulated Blast Furnace Slag (GGBS), Silica Fume, Alccofine, Metakaolin, namely mineral admixtures used as partial or full replacements to the OPC. This present paper reports the properties of GPC made with Flyash, GGBS, and Alccofine for Mix M40- grade concrete the outcomes were contrasted with Nominal concrete which is made using 100 percent cement, Fly ash content of 50% was kept constant throughout the investigation whereas GGBS and Alccofine content varied with an interval of 5%. The concrete was tested for workability, strength, and durability aspects, an increment in the slump, and in the strength was noted, and great resistance was observed under the acid attack test for a GPC mixes, a combination of 50% Fly ash, 35% GGBS, and 15% Alccofine GPC mix was shown optimum results.

“…[2]. Regardless of the materials, fly ash blending is becoming increasingly common because of the technical challenges of coal plants, lower emissions of greenhouse gases from businesses [3]. The volume shift in montmorillonite clay may cause damage to a structure, sidewalk, roadways, pipes, basement floors, and foundations.…”

Supplemental cementitious material made from rice husk combustion is Alccofine. The influence on the strength and durability qualities is experimented in this research. Six different concrete mixes with differing concentrations of Alccofine and cement were prepared for the investigation. The concrete’s durability was further evaluated by absorption and quick permeability testing. The influence of Alccofine, a supplemental cementitious material, on the strength and durability qualities of concrete is investigated in this research. A series of laboratory studies were conducted in which varying quantities of Alccofine were added into the concrete mix. According to the results of the study, using Alccofine as substitute may greatly better the strength. The addition of Alccofine enhanced the compressive strength, with the greatest strength reached at a replacement level of 15%. Furthermore, it reduced the porosity, resulting in increased durability features such as resistance to water and chloride ion penetration. The research also discovered that adding Alccofine resulted in denser microstructure, which contributed to its increased mechanical qualities and durability. Finally, the study results indicate that using a supplemental material has the potential to increase its strength and durability.
