Concrete is an essential construction material, and infrastructures, such as bridges, tunnels, power plants, consume large quantities of it. Future infrastructure demands sustainability issues necessitate the adoption non-conventional supplementary cementitious materials (SCMs). At same time, global labor shortages are compelling conservative sector to implement autonomous digital fabrication methods, 3D printing. This paper thus investigates feasibility using oil shale ash (OSA) SCM in...
This study investigates the fresh state and hardened mechanical durability properties of 3D-printed concrete. The tests focused on its anisotropic behavior in response to different load orientations. Compressive, flexural, splitting tensile strengths were evaluated relative print layers orientation. Results showed that compressive strength varied significantly, achieving 85% cast sample when was applied parallel ([u] direction), 71% perpendicular object’s side plane ([v] while only reaching...
Abstract Huge quantities of fly ash and bottom are generated from thermal power plants it presents great concern for country, mainly due to the environmental effects. In this study, ashes were characterized technical radiological aspects. Health effect activity radionuclides 226 Ra, 232 Th 40 K was estimated via radium equivalent (Raeq), external hazards index (H ex ), absorbed dose rate (D) annual effective (EDR). The specific surface area (40.25 m 2 g−1 particle density (1.88 g cm −3 ) LOI...
This study investigated the influence of different cooling regimes on microstructure and consequent reactivity belite-sulfoaluminate clinkers. The cement clinkers were synthesized by incorporating secondary raw materials, such as titanogypsum bottom ash, to natural materials. Clinker phases determined Rietveld quantitative phase analysis, while distribution morphology incorporation substitute ions in characterized scanning electron microscopy using energy-dispersive X-ray spectroscopy...
The potential use of steel slag from treated in belite-sulfoaluminate cements was investigated this study. Cement clinkers with two phase compositions were synthesized, allowing the incorporation different amounts slag. composition and microstructure cement at three sintering temperatures studied by X-ray powder diffraction Rietveld method, as well scanning electron microscopy energy dispersive spectrometry. results showed that targeted achieved a temperature 1250 °C. However, higher amount...
The cement industry could potentially consume large amounts of solid industrial waste in order to improve its sustainability. suitability selected quarry and mine as secondary raw materials (SRM) was examined for the sustainable production following concept a circular economy. chemical, mineralogical, radiological characterization SRM conducted this study. Its potential use low-carbon low-energy belite-sulfoaluminate investigated by incorporating into clinker. Various methods were used...
The bottleneck in the process for increasing production of low CO2 mineral binders, based on BCSA (belite sulfoaluminate) clinkers, is availability Al-rich raw materials. For that purpose, a new registry Al-containing secondary residues (industrial and mine waste) has been developed presented this paper. methodology creating consists three main steps: Gathering ideas, consolidation implementation. In order to achieve this, following was adopted: Analysis similar registries by potential...
The increase in industrial waste generation presents a global problem that is consequence of the needs modern society. To achieve goals EU Green Deal and to promote concept circular economy (CE), valorization residues as secondary raw materials offers pathway economic, environmental, energetic, social sustainability. In this respect, Al-containing from alumina processing (red mud), thermal power plants (fly ash bottom ash), metallurgy (slag), well other industries, present valuable mineral...
The potential re-use of red mud in the building and construction industry has been subject research many scientists. presented is a contribution to solution this environmental issue through synthesis materials based on mud. A promising way recycling these secondary raw alkali-activated binders or alkali activated materials. Alkali-activated inorganic are new class obtained by activation precursors mainly constituted silica, alumina low content calcium oxide. Since contains radioactive...

<p>Al-rich mineral resources are one of the essential components for production novel sustainable binders. Belite-sulfoaluminate (BCSA) cements, which considered as low-carbon and low-energy, allows substitution natural raw materials with secondary ones. In East-Southeast European countries (ESEE) there huge amounts various industrial mine residues that either landfilled or currently have a low recycling rate. These generated from mining activities (mine waste) by product...
<p>Various industrial residues that are either landfilled or currently have a low recycling rate could represent important secondary mineral resource potential for the construction sector. An ever-increasing sector causes increased demand cement-based materials and consequently implies in increase of CO<sub>2</sub> emission. Belite-sulfoaluminate cements potentially an alternative cementitious binder to ordinary Portland cements, due lower embodied...
