This research pioneers nano-engineered concrete formulations to address accelerated degradation in harsh environments (seawater, acidic solutions, household wastewater). Conventional concrete suffers severe compressive strength loss (25 % in seawater, 56 days) and 35 % increased water absorption due to sulfate/chloride-induced microcracking and portlandite dissolution. Our solution integrates polycarboxylate ether superplasticizers (1 % bwoc) for reduced capillary porosity, vinsol resin air-entrainers (0.02 % bwoc) creating discontinuous micro-bubble barriers, and gluconic acid retarders (0.5 % bwoc) enabling homogeneous C-S-H nucleation. Rigorous testing under ASTM/EN protocols revealed nano-modified specimens limit strength degradation to 15 % in seawater and absorption increase to 15 % outperforming ordinary concrete by 40 % in key durability metrics. Advanced characterization (SEM-EDS/XRD/mercury porosimetry) confirmed refined pore structures (< 50 nm dominant pore diameter vs. > 200 nm in controls) and inhibited ettringite formation. The study establishes admixtures as multi-functional nano-modifiers that obstruct ionic diffusion pathways through electron barrier effects and optimized hydration kinetics, providing a transformative approach for marine and chemical-exposure infrastructure. |
