Moisture-induced Debonding in Concrete-epoxy Interface
Concrete-epoxy interface can be found in many strengthened or retrofitted structures, especially in Hong Kong where concrete structures are the majority. In practice, epoxy is usually used in repairing concrete structures because of its excellent adhesion, chemical and heat resistance, good mechanical properties and electrical insulating properties. The bond between concrete and epoxy has been ...
متن کاملUnderstanding and Assessment of Debonding Failures in FRP-Concrete Systems
Failures in FRP-strengthened reinforced concrete (RC) members may occur by flexural failures of critical sections or by debonding of FRP plate from the RC beams. Debonding in the FRP/adhesive/concrete interface region may cause a significant decrease in member capacity leading to a premature failure of the system. There is a need for improved knowledge of the debonding processes under mechanica...
متن کاملPullout Load Analysis of Reinforced Concrete Anchor Shafts
In this paper, results obtained in both conventional and finite element analysis of straight and belled anchor shafts subjected to a pullout force are presented. In numerical analysis, it is assumed that no drainage takes place during the anchor pullout. Comparisons between two conventional methods of analysis for ultimate pullout load and the results obtained by the finite element analysis are...
متن کاملOptimization of Mortar Phase in Concrete – Using Particle Packing Concept
Submitted: Jul 2, 2013; Accepted: Aug 12, 2013; Published: Aug 29, 2013 Abstract: Concrete mix design involves determination of relative proportions of powder contained in the binder system, granular aggregates and water. The theory of particle packing (TPP) concepts can be used for rational proportioning of concrete mixtures analytically based on the measured properties of individual ingredien...
متن کاملOrientation of Steel Fibers in Magnetically Driven Concrete and Mortar
The orientation of steel fibers in magnetically driven concrete and magnetically driven mortar was experimentally studied in this paper using a magnetic method. In the magnetically driven concrete, a steel slag was used to replace the coarse aggregate. In the magnetically driven mortar, steel slag and iron sand were used to replace the fine aggregate. A device was established to provide the mag...
