Frontiers of Structural and Civil Engineering 2022, Volume 16, Issue 5,   Pages 624-637 doi: 10.1007/s11709-022-0832-2

Abstract: In the past, glass fiber-reinforced polymer (GFRP)-reinforcement has been successfully applied in reinforcedconcrete (RC) structures where corrosion resistance, electromagnetic neutrality, or cuttability wereHowever, especially the low modulus of elasticity of GFRP limited its wide application as GFRP-reinforcedmembers usually exhibit considerably larger deformations under service loads than comparable steel-reinforcedas the plastic deformations after the earthquake were considerably less pronounced than in the steel-reinforced

Critical review of recent development in fiber reinforced adobe bricks for sustainable construction

Mahgoub M. SALIH, Adelaja I. OSOFERO, Mohammed S. IMBABI

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 4,   Pages 839-854 doi: 10.1007/s11709-020-0630-7

Abstract: This paper presents a state-of-the-art review of research on the utilization of fibers (predominantly derived from waste materials) as reinforcement in adobe brick production. Recycling of these wastes provides sustainable construction materials and helps to protect the environment. Specimen preparation and test procedures are outlined. The effects of addition of these wastes on the physical and mechanical properties of adobe bricks as presented in the literature, are investigated. The main results for each additive are presented and discussed. It is concluded that improved adobe brick properties can be expected with the addition of combination of waste additives. The use of waste materials in the construction industry is generally of interest and useful for engineers and designers seeking sustainable solutions in construction. It is also of interest to researchers actively seeking to develop methodical approaches to quantifying, optimising and testing the performance in use of such waste material additives.
