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...

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...

Garcia Ramirez, Bernardo

Although significant progress in the modelling of the nonlinear response of reinforced - concrete (RC) structures at the element level has been achieved in the past decades, reliable and accurate analysis models at the system level for RC structures are scarce. Due to the complexity of elements...

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...

This study is part of a joint Canada-India research program to effect sustainable construction. Alberta generates a significant amount of waste from agricultural- and forest-based industries. Similarly, India has lots of sugar cane bagasse waste. Researchers in both countries want to use these...

Magnesium potassium phosphate cement (MPPC) is an innovative chemically bonded cement formed by the reaction of magnesium oxide and monopotassium phosphate. Concrete produced using a MPPC binder can exhibit faster strength gain and results in lower overall environmental impacts from greenhouse...

Magnesium potassium phosphate ceramics are from the family of phosphate-based cements which can be used as alternatives to Portland cements. In this study, concretes and wood composites were produced using magnesium potassium phosphate ceramic binders and supplementary materials including fly...

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...

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 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...
