“…U svijetu se povećava potražnja i interesovanje za agregate iz netradicionalnih izvora kao što su industrijski nusprodukti i reciklirani otpad pri gradnji i rušenju [1]. Mnogi istraživači pokušavaju da prouče GBFS (granulirana zgura visoke peći) u proteklim godinama kako bi procijenili njene osobine i njeno ponašanje [4]. Naravno, neophodno je obezbijediti ekonomski isplativu i ekološki prihvatljivu gradnju.…”

“…The demand for interest in non-traditional aggregates such as industrial by-products and recycled waste from building and demolition increasingly spreads worldwide [1]. Many researchers studied GBFS (granulated blast furnace slag) in the previous years in order to assess its properties and behaviour [4]. Normally, it is necessary to provide economically profitable and ecologically acceptable construction.…”

“…Though there are many researches executed upon the replacement of fine aggregate in concrete with other industrial wastes and by-products such as waste foundry sand [8,9], bottom ash [10,11], waste glass [12,13], marble waste [14, [15], crumb rubber [16][17][18], plastic PET fibres [19,20], iron slag [21,22], basaltic pumice [23,24], rice husk [25,26], waste tiles [27] and fly ash [28,29], there are limited studies incorporating GGBS as fine aggregate [30] due to its finer nature. Nevertheless, in a detailed study [31] when granulated blast furnace slag (GFS), which has a particle size similar to river sand, is used as fine aggregate in concrete at 20%, 40% and 60%, better figures were noted in the quality of concrete when the GFS % is increased at both 0.45 and 0.5 water/cement ratio.…”

Scarcity of the construction materials, peculiarly the natural river sand has become a serious threat in the construction industry. Though many researchers of developed and developing countries are trying to find alternative sources for the same, the complete replacement of the fine aggregate in concrete is crucial. Geopolymer sand developed from the Industrial waste (Ground granulated blast furnace slag - GGBS) is an effective alternative for the complete replacement of the natural sand. The GGBS based geopolymer sand (G-GFA) was tested for physical and chemical properties. Upon the successful achievement of the properties in par with the natural river sand, the fresh properties (fresh concrete density & slump) and hardened properties (compressive strength, tensile strength & flexural strength) of the concrete specimens developed with G-GFA were studied. The G-GFA is obtained by both air drying (AD-G-GFA) and oven drying (OD-F-GFA) after the dry mixing of the alkaline solution and GGBS for about 10 min. Thus, developed fine aggregates were studied separately for the fresh and hardened concrete to optimize the feasible one. Superplasticizer of 0.4% is included in the concrete mix to compensate the sightly hydrophilic nature of the fine aggregates produced. The mechanical properties of the concrete with G-GFA are observed to be more than 90% close to that of the concrete developed with natural river sand. Thus, both the fresh and mechanical properties of the G-GFA concrete specimens resulted in findings similar to those of the control specimen developed with natural river sand reflecting the plausibility of G-GFA as a complete replacement choice to the fine aggregate in the concrete industry. The flaky GGBS particles merge well with the alkaline solution at room temperature itself since the former gets dried at elevated temperatures. Thus, more feasible fresh concrete properties and mechanical properties were recorded for the AD-G-GFA than the OD-G-GFA.

“…To overcome this problem, an alternative fine aggregate is essential. Researchers throughout the world have studied the use of slag [13], quarry dust [14], granite fines [15][16][17][18], copper slag [19,20], etc. as replacement of conventionally used natural sand as fine aggregate for the manufacture of concrete.…”

This paper presents the properties of blended geopolymer concrete manufactured using fly ash and ultrafine Ground Granulated Blast Furnace Slag (UFGGBFS), along with the copper slag (CPS) as replacement of fine aggregate (crushed stone sand). Various parameters considered in this study include different sodium hydroxide concentrations (10M, 12M and 14M); 0.35 as alkaline liquid to binder ratio; 2.5 as sodium silicate to sodium hydroxide ratio and cured in ambient curing condition. Further, geopolymer concrete was manufactured using fly ash as the prime source material which is replaced with UFGGBFS (0%, 5%, 10% and 15%). Copper slag has been used as replacement of fine aggregate in this study. Properties of the fresh manufactured geopolymer concrete were studied by slump test. Compressive strength of the manufactured geopolymer concrete was tested and recorded after curing for 3, 7 and 28 days. Microstructure Characterization of Geopolymer concrete specimens was done by Scanning Electron Microscope (SEM) analysis. Experimental results revealed that the addition of UFGGBFS resulted in an increased strength performance of geopolymer concrete. Also, this study demonstrated that the strength of geopolymer concrete increased with an increase in sodium hydroxide concentration. SEM results revealed that the addition of UFGGBFS resulted in a dense structure.
