When rubberized, concrete beams lose some of their flexural strength. Conversely, flexural strengthening accounts for a sizeable portion of the structural applications for external carbon fiber reinforced polymers (CFRP) sheets that strengthen reinfo

Abstract Lightweight concrete (LWC) is one of the most important building materials nowadays. Many research studies were focused on LWC produced using lightweight aggregates. However, limited work was cited for LWC produced using polystyrene beads. I

This paper presents the numerical strength prediction of externally carbon fibre reinforced polymer (CFRP)- strengthened concrete beams using a traction-separation law. From reported experimental observations, the externally CFRP-strengthened concret

Strain-hardening cementitious composites (SHCC) improve the performance of tensile properties and crack control. In this investigation, SHCC formulated based on desert sand could be used to strengthen structural members by improving their load-carryi

Although there are many advantages to using rubber to produce reinforced concrete substrates, there are still few applications for rubberized concrete substrates like beams, where the mechanical properties of rubber-infused concrete, such as flexural
