Investigation of Reinforced Concrete Slabs Strengthened with Shear-Connected Mesh Jacketing

This study investigates the effectiveness of an integrated repair technique for corroded reinforced concrete (RC) slabs using mechanical surface preparation, steel dowels, supplementary reinforcement mesh, and shotcrete jacketing. Six standard-scale RC slab specimens were tested under static two-point loading: one unco...

Eco-friendly protective coating made from geopolymer mortars for conventional concrete in a marine environment

Geopolymer mortar offers an eco-friendly way to protect concrete in harsh environments. Affordable materials such as fly ash (FA) and rice husk ash (RHA) improve sustainability, with RHA providing silica. The long-term effects of geopolymer and Portland cement in marine environments, especially under severe sulfate att...

Experimental Evaluation of Concrete Structural Properties with Recycled Coarse Aggregate and Rice Husk Ash

The present work examines the mechanical and structural performance of concrete in which rice husk ash (RHA) partially replaces cement and recycled concrete coarse aggregate (RCA) serves as an alternative to natural coarse aggregate (NCA). Fifteen concrete mixtures were prepared with RCA replacement levels of 0%, 25%,...
