Ultra-high performance concrete (UHPC), an extraordinary category of cementitious composites, showcases unparalleled mechanical and durability properties. Given the current disparity in carbon levels environmental hazards associated with cement production, various types biochar materials have been incorporated into composites. This approach offers a mutually advantageous solution, effectively reducing CO2 emissions while simultaneously preserving natural resources. study aims to evaluate use palm shells, waste biomass, as substitute for aggregate UHPC matrix. The investigation focused on replacing 1–40 % sand, specifically considering apricot, date, peach shells at 8 replacement. A comprehensive analysis was carried out total 12 combinations, encompassing control group. For biochar-mortar admixtures, decrease workability density were observed. Replacing 1 sand mortar improved compressive strength, but increasing dosage weakened it. Biochar-mortar demonstrated dual impact drying shrinkage. Mixtures higher dosages showed slight increase permeability. Incorporating led slightly lower electrical flux value. SEM images obtained, highlighting compact morphological structure seen both mortar. MIP test nearly 1.6 times 2-dimensional porosity, from 10.49 (control) 16.83 sample which had 30 biochar. Based results it could be concluded that possesses capability, enhances properties when used partial replacement conventional fine minor fractions.

This experimental study delves into the impact of Multi-Walled Carbon Nanotubes (MWCNTs) on Geopolymer Concrete (GPC), investigating their effect compressive strength and load deflection behaviour. MWCNT concentrations ranging from 0.02% to 0.16% were employed examine influence structural performance 1500 mm (L) x 150 (B) (D) concrete beams. The findings derived this investigation yielded several significant conclusions. outcome research identified optimum dosage for enhancing at 0.12%, resulting in a substantial 29.78 MPa. However, surpassing concentration led decline strength. Notably, remarkable 26.62% increase was observed with 0.12% when compared reference specimens. In analysing performance, it that energy absorption capacity (EAC) exhibited consistent behavior up 0.6% addition MWCNT. At inclusion, EAC GPC reached its peak value 6116 kN.mm. Stiffness maintenance mirrored trends 0.1% MWCNT, beyond which decrease stiffness noted higher concentrations. Furthermore, Density Index (DI) beams sustained after DI began increase. Flexural Toughness Factor (FTF) retained 0.06%. declined flexural Additionally, Scanning Electron Microscopy (SEM) images revealed denser internal structure optimal Subsequent additions increased agglomeration, potentially hampering effective interaction between binder, activator within matrix. These contribute obtain optimised superior applications.
