Modelling Repair Techniques for Reinforced Concrete Bridge Barriers using Glass Fibre Reinforced Polymer Bars
DownloadSpring 2021
In an era where bridge deterioration due to corrosion has become evident and a pressing concern for future reinforced concrete bridge construction, glass fibre reinforced polymer (GFRP) reinforcement has emerged as a feasible alternative to steel due to its superior corrosion resistance. Research...

Bond Performance between Lightweight Concrete with Crumb Rubber and Glass Fibre Reinforced Polymer Bar
DownloadFall 2017
For any reinforced concrete structure, the bond between concrete and the reinforcement bar is the most important parameter from structural standpoint. Notwithstanding numerous prior studies on describing this interaction for different reinforcing bars, not enough understanding exists for fibre...

Moosavi Nanehkaran, Seyed Abdol Hadi
Although the reliability levels of structural steel and reinforced concrete structures designed to the Canadian codes and standards have been investigated substantially in the past four decades, studies on the reliability of masonry structures are limited. Based on some preliminary studies in...

Precast concrete insulated wall panels (IWP) are thermally and structurally efficient systems commonly used in construction. Although their flexural performance has been studied extensively, there are limited studies on thermal bowing in IWP. Bowing causes unwanted deflections, stresses on the...

Shear Behaviour of Concrete Slabs and Beams Reinforced with High-Performance ASTM A1035 Steel
Download2013-09-30
Lubell, Adam S., Desalegne, Admasu S.
High-performance steel bars manufactured to conform to ASTM A1035-11 have different metallurgy and microstructure than conventional reinforcing steel. These changes result in an effective yield strength significantly higher than conventional ASTM A615 steel while also being less susceptible to...

The present study has focused on the effects of Powdered Activated Carbon (PAC) in fly ash on the air-entraining admixture demand and consequent properties of concrete. An extensive laboratory test program was completed during this investigation. Three series of mixes were designed to evaluate...

Premature corrosion of reinforcing steel is a cause of concern for steel-reinforced concrete structures, since it causes them to deteriorate before their design operational life is attained. The Use of fiber-reinforced polymer (FRP) bars in reinforced-concrete (RC) structures has been shown to...

Bindiganavile, V.S., Lubell, A.S., Shoaib, A.
Hooked end steel fibers were included between 0~1% by volume to provide enhanced shear resistance to three different types of steel fiber reinforced concrete (SFRC) namely, a regular concrete mix, a lightweight aggregate mix and a high strength mix. The test results at the material scale showed a...

The most common detrimental processes that lead to reduction in durability in reinforced concrete elements are shrinkage, sulphate attack and chloride attack. Shrinkage is a dimensional instability chiefly caused by a loss of moisture in the hydrating cement paste. Soluble sulphate ions take part...
