Rehabilitation of Reinforced Concrete Beams

open access: yesTikrit Journal of Engineering Sciences, 2017
The concrete structures are often exposed to damage as a result of several factors including, environment, design, and other factors, and because of the high cost and long time needed for reconstruction of the damaged buildings, it become necessary to consider methods for rehabilitation of the damaged structural member in the building.

Treatments on Polypropylene Macro Synthetic Fibers for Improving Adhesion in Structural Concrete Reinforcement: A Systematic Review

open access: yesJournal of Applied Polymer Science, EarlyView.
Surface functionalization of polypropylene macrofibers to enhance fiber‐matrix interfacial bonding. ABSTRACT Concrete is the most used higher compressive strength‐building material, albeit brittle to tensile, and flexural loads. Polypropylene (PP) synthetic polymeric macrofibres are commonly employed as reinforcement material to prevent this situation ...

Flexural capacity of concrete beams reinforced with steel and fibre‐reinforced polymer (FRP) bars

open access: yesJournal of Civil Engineering and Management, 2004
Although much research on concrete beams reinforced with fibre‐reinforced polymer (FRP) rods has been conducted in recent years, their use still does not receive the attention it deserves from practicising engineers. This is attributed to the fact that

Sailing From Penalties to Accountability: Business Strategies and Governance for Firms to Innovate After Environmental Misconduct

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Firms' continuous pursuit of making a profit in the competitive market may ignore the actions related to environmental responsibilities. This set of actions for financial gains constitutes environmental misconduct, which not only harms ecosystems and communities but also brings reputational damage. Negative press and social media amplification
