MECHANICAL BEHAVIOR OF HUME PIPES COVERED WITH REINFORCED CONCRETE

Mechanical Behavior of Hybrid Fiber Reinforced High Strength Concrete with Graded Fibers

Brittleness, which was the inherent weakness in High Strength Concrete (HSC), can be avoided by reinforcing the concrete with discontinuous fibers. Reinforcing HSC with more than one fiber is advantageous in an overall improvement of the mechanical performance of the composite. In this experimental study, Hybrid Fiber Reinforced High Strength Concrete (HyFR-HSC) mixes were formed by blending si...

Risk-based Replacement Strategies for Deteriorating Reinforced Concrete Pipes

Water distribution networks comprised of underground reinforced concrete pipes deteriorate with time due to environmental conditions, such as chloride-induced corrosion and differential soil movements [1]. If the pipes in these networks are not periodically replaced, they will eventually fail. Strategies for replacement for these pipes depend on 1) the risks associated with failure of a water d...

Mechanical Behavior of Concrete, Made with Micro-Nano Air Bubbles

Nano materials have been widely used in laboratory and industrial scales in order to improve various properties of concrete and concrete mixture. The mainstream practice of the researches in this field is to add metallic nano-particles into the concrete mixture. The present research focuses on adding Micro-Nano Air Bubbles (MNAB) into water before mixing it with aggregate and cement mixtures. I...
