Adhesion Dynamics of Ulva -Diatom Biofilms on Mortar Surfaces in Dynamic Marine Environments and Their Mechanistic Roles in Substrate Performance Deterioration

Abstract Considering that current research on biocorrosive building materials is predominantly conducted through field exposure in marine environments or static laboratory cultivation, field tests struggle to achieve precise quantification of individual biological species’ effect...

Bending reinforcement of cedar glulam beam with inserted GFRP and BFRP plates

This study investigates the bending performance enhancement of glued laminated timber (glulam) beams reinforced with glass fiber reinforced polymer (GFRP) and basalt fiber reinforced biopolymer (BFRP) containing biomass material in its matrix resin. The glulam beams were reinforc...

Field verification of the effect of rail pad stiffness on rail corrugation growth

This study presents a field-based investigation into the influence of rail pad stiffness on the growth of rail corrugation through regular measurements of rail surface roughness on an in-service metro line. Rail corrugation is a critical issue in railway systems due to its contri...
