... as a promising low-carbon alternative, utilising industrial waste materials such as fly ash as binders. While previous studies have explored the mechanical properties of geopolymer concrete, limited attention has been given to its microstructural behaviour using ultrafine siliceous fly ash and the optimisation...

... ), scanning electron microscopy ( SEM ), and fractal theory to characterise the microstructure of FSC incorporating 0, 0.06, and 0.10 wt.% CNTs, while evaluating its mechanical and fracture properties at 3, 7, and 28 days. Results indicated that the optimal 0.06 wt.% CNTs dosage enhanced the 7-day...

.... This experimental study aims to investigate the effect of adding crushed ceramic waste (CCW) and crushed brick waste (CBW) on the bulk density, workability, compressive and flexural strengths, water absorption and microstructural properties of dune sand mortar. To determine changes in porosity, the study uses...
