This study led to the creation of empirical models of the properties of high-performance self-compacting concrete (HPSCC) with inductionfurnace slag (IFS) added as an extra cementitious ingredient. The ingredients were Portland cement, IFS ranging from 0 to 50% by cement weight, granite, river sand, water, and superplasticizer. Using a slump flow test, the filling-ability property of the newly produced HPSCC was investigated. Similarly, a compressive strength test was used to determine the hardened HPSCC's compressive strength. Using already established scientific ideas, the empirical model of the filling-ability characteristic of the fresh HPSCC was generated, on the basis of the slump flow and the volume of the paste of the fresh concrete. Likewise, the empirical model of the compressive strength of the hardened HPSCC was generated, based on the combination of the parameters of the strength developed over time, with the strength developed, due to the addition of the IFS. Based on these, the empirical model of the fillingability property of the fresh HPSCC was ρ r s f 2 = 0.002 ( 1 - V P ) - 11.34 {{{\rho _r}} \over {{s_f}^2}} = 0.002{\left( {1 - {V_P}} \right)^{ - 11.34}} , while that of the compressive strength of the hardened HPSCC was f c ( t ) = t 4.52 + 0.78 t ( − 0.0109 ( P i f s ) 2 + 0.2632 P i f s + 52.446 ) {f_c}\left( t \right) = {t \over {4.52 + 0.78t}}\left( { - 0.0109{{\left( {{P_{ifs}}} \right)}^2} + 0.2632{P_{ifs}} + 52.446} \right) . The empirical models were then validated using test data from this work. Strong links between the measured and the predicted values were identified by the empirical correlations, where the coefficient of determination (R2) value for the filling ability property, gave above 94% and the R2 value for the compressive strength, gave above 86%. The estimated slump flow and the compressive strength were approximately equal to the experimental values. The outcomes demonstrated that IFS may be utilized to produce an eco-friendly and environmentally sustainable HPSCC. The models can be adopted in designing HPSCC containing IFS as a supplementary cementitious material (SCM) and in predicting its filling-ability and compressive strength, which will benefit the construction industry.

“…Portland cement is one of the primary materials used in construction. Approximately 3 billion tons of Portland cement is produced every year [4]. However, for every ton of Portland cement produced, 0.55 tons of CO 2 is created via chemical reactions and 0.39 tons of CO is generated by combustion and fuel emissions during the production process, which adds up to approximately 0.94 tons of CO 2 [5].…”

This study investigates novel geopolymers by combining Reactive Ultra-fine Fly Ash (RUFA) with 4M sodium hydroxide as an alkali activator. Comparing with general fly ash geopolymers, RUFA geopolymer pastes are characterized in terms of compressive strength, microstructure, and crystalline phases. The RUFA geopolymer is successfully obtained as alumina-silicate bonding materials with the same properties as the general fly ash-based geopolymer. The high compressive strength of the RUFA-based geopolymer samples (13.33 MPa) can be attributed primarily to Ca-based alumino-silicate hydration products and Na-based alumino-silicate complexes. This research presents an innovative application for geopolymers using RUFA. In the follow-up study, the influence of synthesis and concentration of alkali activator can be considered in RUFA-based geopolymers.

Many natural minerals [21][22][23], calcined clays [24][25][26], and industrial by-products such as blast furnace slag [27], fly ash [28][29][30][31][32], rice husk ash [33], waste glass [34], and red mud [35] can be used as additional materials for the synthesis of geopolymers [17,36]. Therefore, geopolymer technology is an important solution for industrial waste utilization, the amount of which increases every year [8,17].…”

Nowadays, one very dynamic development of 3D printing technology is required in the construction industry. However, the full implementation of this technology requires the optimization of the entire process, starting from the design of printing ideas, and ending with the development and implementation of new materials. The article presents, for the first time, the development of hybrid materials based on a geopolymer or ordinary Portland cement matrix that can be used for various 3D concrete-printing methods. Raw materials used in the research were defined by particle size distribution, specific surface area, morphology by scanning electron microscopy, X-ray diffraction, thermal analysis, radioactivity tests, X-ray fluorescence, Fourier transform infrared spectroscopy and leaching. The geopolymers, concrete, and hybrid samples were described according to compressive strength, flexural strength, and abrasion resistance. The study also evaluates the influence of the liquid-to-solid ratio on the properties of geopolymers, based on fly ash (FA) and metakaolin (MK). Printing tests of the analyzed mixtures were also carried out and their suitability for various applications related to 3D printing technology was assessed. Geopolymers and hybrids based on a geopolymer matrix with the addition of 5% cement resulted in the final materials behaving similarly to a non-Newtonian fluid. Without additional treatments, this type of material can be successfully used to fill the molds. The hybrid materials based on cement with a 5% addition of geopolymer, based on both FA and MK, enabled precise detail printing.
