Effect of GFRP rebars and polypropylene fibers on flexural strength in high-performance concrete beams with glass powder and microsilica

Autor: Maedeh Orouji, Erfan Najaf

Publikováno v: Case Studies in Construction Materials, Vol 18, Iss , Pp e01769- (2023)

Considering the benefits of GFRP rebars and their lighter weight compared to steel rebars and the sustainability of polypropylene fibers, GFRP rebars and polypropylene fibers are investigated as sustainable materials replacements for steel rebars in

Finite element analysis of the effect of type, number, and installation angle of FRP sheets on improving the flexural strength of concrete beams

Autor: Erfan Najaf, Maedeh Orouji, Kaveh Ghouchani

Publikováno v: Case Studies in Construction Materials, Vol 17, Iss , Pp e01670- (2022)

Using FRP material to strengthen concrete beams is one of the best methods to prevent cracks propagation in the tensile zone. In this article, a concrete beam is modeled using the finite element software Abaqus. In order to investigate the effects of

Improving nonlinear behavior and tensile and compressive strengths of sustainable lightweight concrete using waste glass powder, nanosilica, and recycled polypropylene fiber

Autor: Erfan Najaf, Maedeh Orouji, Seyed Mehdi Zahrai

Publikováno v: Nonlinear Engineering. 11:58-70

Concrete is one of the most extensively utilized building materials that can be produced, and has the potential to release a significant quantity of CO2 into the environment. In this research, through studying lightweight (LW) concrete, attempts are

Effect of glass powder & polypropylene fibers on compressive and flexural strengths, toughness and ductility of concrete: An environmental approach

Autor: Seyed Mehdi Zahrai, Maedeh Orouji, Erfan Najaf

Publikováno v: Structures. 33:4616-4628

Today a wide variety of tools and instruments are made from glass, and they need recycling after being wasted. However, their recycling process could harm the environment. In order to increase concrete ductility and strength against the flexural and
