“…According to recent study, Alccofine (AL), a microfine substance produced as a by-product of the iron ore industry in India, also has pozzolanic properties and can be utilised as a partial substitute for cement in concrete [32]. The workability and mechanical qualities of concrete were significantly improved by employing alccofine as an additive [33,34]. Alcofine considerably enhances concrete's capacity to fill micropores and develops resistance to segregation because of its ultrafine particle size, which also helps to improve the material's mechanical, fresh, and durable qualities.…”

The CO2 emissions from cement have had significant negative consequences on the environment, necessitating the substitution of cement in the production of concrete. This research tends to cover the mechanical characteristics and microstructural studies of concrete formed by replacing some of the cement with Alccofine (AL) by percentages of 5%, 10%, 15%, 20%, 25% and 30% and some of fine aggregate with Glass Powder (GP) by percentages of 10%, 20%, 30%, 40% and 50% in the concrete of the M40 grade. A pozzolanic substance called alccofine and high silica content material called glass powder was extensively utilized in the building industry. When the mechanical properties of concrete were tested at various time periods, the optimal partial cement and fine aggregate substitution was determined to be 20% Alccofine and 50% of Glass Powder. When compared to conventional concrete of the same ratio, the compressive strength of the concrete has been enhanced at 20 percent replacement of AL and 50 percent replacement of GP. Moreover, concrete was subjected to a microstructural examination to observe the hydration process at various time intervals, and the results clearly demonstrated how pores and C-S-H (calcium-silicate hydrate) gel are created in both early ages and later ages. According to the study's findings, cement may be replaced in part without impairing its properties and can help lessen the impact of CO2 on the environment.

“…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.
