Fiber-reinforced cementitious matrix (FRCM) and steel-reinforced grout (SRG) have been increasingly applied as externally bonded reinforcement to masonry members in the last few years. Unlike fiber-reinforced polymer (FRP), FRCM SRG good performance when exposed (relatively) high temperature compatibility with inorganic substrates, they can be wet surfaces at (reasonably) low temperatures. Alth...

This article investigates the potential detrimental effects of cyclic load during installation externally bonded (EB) carbon fiber-reinforced polymer (CFRP) on a damaged reinforced concrete (RC) structure. Four RC specimens were tested in three point bending to study consequences crack opening-closure epoxy-curing period. A first specimen (without CFRP) was loaded monotonically up failure serve...

AIM To compare the retention of amalgam restorations in bonded amalgam restoration and restorations with undercuts. BACKGROUND With improvement in adhesive technology problem associated with conventional preparation for amalgam restorations mainly compromised resistance form of tooth structure have been largely overcome. MATERIALS AND METHODS Forty caries free extracted molars were used. A ...

CFRP is an alternative technique for cracking control of high-chloride reinforced concrete (RC) beams. This research, therefore, investigates the strength performance and failure mode behaviour RC beams incorporated with sea sand bonded externally carbon fibre polymer (CFRP) plate. Sea used as a 100% replacement fine aggregate. Three batches were carried out in this including beam (no neither C...

This paper enumerates the effectiveness of externally bonded Hybrid Fiber Reinforced Polymers (HyFRP) laminates on reinforced concrete beams for flexural strengthening. A total 5reinforced size 150 x 250 in cross section and length 3000mm were considered this study. All tested four-point bending over a simple span 2800 mm. Of above five beams, one beam served as reference other four HyFRP lamin...
