HPC is an innovative high quality, and cost-efficient concrete compared to normal-strength concrete that meets the new generation’s desire for complex engineering structures. The past two decades have seen the rapid use of high-performance concrete (HPC) in constructing critical structural elements of super-tall buildings and other complex architecture, engineering, and construction (AEC) structures worldwide. Therefore, it is recommended that MCC addition within 10% cement replacement be adopted for low W/B Class I HPC at no deleterious results on mechanical and microstructural properties of the concrete. The MCC incorporation at 10% cement replacement best improved the porosity of HPCs at a later age resulting in increased mechanical and microstructural properties of tested samples. The MCC addition increases the slump flow of HPCs at 5–15% cement replacement. The XRD results show that the MCC was majorly an illite-based clay mineral calcined at a maximum temperature of 650 ☌, as revealed by the TGA. At the same time, the SEM image presents particles of broad, solid masses with a wider surface area of irregular shape. The XRF result shows that the oxide composition of MCC confirmed the pozzolanic material requirements with recorded high useful oxides content. The MCC’s effect on the workability and mechanical properties (compressive, splitting tensile and flexural strengths) and microstructure (morphology and crystalline phases) of hardened MCC-based HPCs were determined. To obtain the properties of the cementitious materials, the chemical composition, mineral phases, morphology, calcination efficiency and physical properties were quantitatively analysed using the advanced techniques of X-ray fluorescence (XRF), scanning electron microscopy/energy dispersive X-ray (SEM/EDX), X-ray diffraction (XRD), Fourier transform infrared/attenuated total reflection (FTIR/ATR), thermogravimetric analysis (TGA), laser particle sizing and Brunauer–Emmett–Teller (BET) nitrogen absorption method. #s 4,395,937, 4,320,256 and 4,356,856).The work described in this paper has been performed to determine the potential use of meta-illite (K yAl 4(Si 8-y) O 20(OH) 4) calcined clay (MCC) as a supplementary cementitious material (SCM) in a binary Portland cement (PC) for high-performance concrete (HPC) production. * "Flow", "Flow Free", and the Flow Free icon are trademarks registered internationally, including in the United States, to Big Duck Games®, LLC (reg. * Clean, colorful graphics and fun sound effects * Game Center achievements and cloud sync of your progress * Optimized touch controls for smooth, satisfying play * Carefully crafted, high-quality puzzles ranging from easy to extreme! * Daily puzzles: new levels every day, never run out So, give Flow Free: Hexes a try, and experience "mind like water"!
