Abstract Carbon nanotubes (CNTs) have received extensive attention due to their exceptional properties and wide range of applications. However, the agglomeration CNTs in aqueous solutions organic solvents significantly limits large-scale application. In this study, microscopic morphology dispersion stability CNT suspensions were analyzed, most suitable surfactant study was selected. The preparation parameters optimized, uniaxial compression tests conducted on carbon nanotube concrete (CNTC) prepared using optimized parameters. Scanning electron microscope analysis used investigate improvement microstructure by CNTs. Transmission micrographs polyvinyl pyrrolidone (PVP)-CNT exhibited a uniformly distributed cross-linked network. absorbance reduction ratio PVP-CNT after standing for 90 days 13.75 22.41%, respectively. first increased then decreased with increasing dispersant ultrasonic time power ratio. Compared that plain concrete, compressive strength CNTC improved, maximum increase 18.15% when content 0.10%, failure mode typical shear characteristics. PVP-to-multiwalled mass 4:1, an 20 min, 60%. These are ideal choices preparing cement-based composite suspensions.

The ceramic industry produces a significant volume of waste (CW), representing around 20-30% its the entire output. mostly comes from challenges noticed in manufacturing process, overproduction, and damage to products. Considering substantial worldwide production ceramics, it is crucial efficiently handle recycle this promote sustainability efforts. This study explores conversion into fine aggregates suitable for paver blocks. Currently, variety assessments are being conducted determine effectiveness these enhanced evaluations involve aspects like compressive strength, water absorption (WA), dry density, flow table measurements, ultrasonic pulse velocity (UPV), rebound hammer tests. results indicate that replacing natural with up 30% CW significantly improves strength (CS) Rebound provides useful information optimising content blocks, contributing development sustainable economical construction materials. Furthermore, focusses on minimising landfill preserving resources.

Abstract The degradation of concrete structures is significantly influenced by water penetration since serves as the primary vehicle for movement harmful compounds. process capillary absorption widely recognized a crucial indicator durability unsaturated concrete, it allows dangerous substances to enter composite material. capacity intricately linked its pore structure, inherently porous. main goal this work create an innovative predictive tool that assesses porosity analyzing components using machine-learning (ML) framework. Seven distinct batch design variables were included in generated database: fly ash, superplasticizer, water-to-binder ratio, curing time, ground granulated blast furnace slag, binder, and coarse-to-fine aggregate ratio. Four distant ML algorithms, including AdaBoost, linear regression (LR), decision tree (DT), support vector machine (SVM), are utilized infer generalization capabilities algorithms estimate accurately. RReliefF algorithm was implemented calculate significant features influencing porosity. This study concludes comparison alternative techniques, AdaBoost method demonstrated superior performance with R 2 score 0.914, followed SVM (0.870), DT (0.838), LR (0.763). results evaluation indicated binder possesses remarkable influence on concrete.
