Techniques and Procedures for Bonded Concrete Overlays

An Analytical Method for the Evaluation of the RC Columns Capacity Strengthened by Concrete Overlays

An Investigation on In-situ Strength and Bonding Strength of Polymer Modified Concretes (PMC) as Repair Overlays on Conventional Concrete Substrate

Polymer modified concrete (PMC) consists of Portland cement concrete with a polymer modifier. Its advantages are proper bonding strength to substrate concrete, high tensile and flexural strength and low amount of shrinkage and permeability. Using PMC overlays can be considered as a method for preservation of damaged concrete structures due to their suitable performance and durability. In this r...

Durability of Self-compacting Lightweight Aggregate Concretes (LWSCC) as Repair Overlays

For rehabilitation of damaged concrete structures, the durability of repair overlay is a very important issue. Self-compacting concretes (SCC) are known as a suitable repair overlay materials. In this study, the durability of different self-compacting lightweight aggregate concretes (LWSCC) and effect of lightweight aggregate type on them is investigated. 3 mix designs of LWSCC containing three...

Durability Considerations for FRP-Strengthened RC Structures in the Australian Environment

1.0 Introduction It is now reasonably well established that reinforced concrete (RC) structural elements can be strengthened/retrofitted/repaired by bonding high-strength fibre reinforced polymer (FRP) composites. Such reasons include steel reinforcement corrosion, construction flaws, change in loading or structure usage, or damage from impact or seismic events. Traditional methods of repair ca...
