  • Flexural behavior and crack development of reinforced geopolymer slabs with longitudinal voids: an experimental study
    Yasmin Hefni Abdel Aziz, Abeer El Malky, Taha A. El-Sayed
    Scientific Reports, 2026
    Geopolymer concrete, produced from the alkali activation of aluminosilicate-rich by-products such as fly ash, presents a sustainable, low-carbon substitute for standard Portland cement. Despite its acknowledged mechanical and durability advantages, researchers have not thoroughly examined the flexural performance of reinforced GC slabs particularly hollow-core designs. This paper offers a comprehensive experimental and theoretical assessment of reinforced GC solid and hollow-core slabs to fill this gap. Seven slabs were tested under four-point loading tests: two solid specimens (OPC and GC) and five hollow-core GC slabs featuring varying void sizes and shear-span-to-depth ratios (a/d). The investigation concentrated on reaction to cracking, ultimate flexural capacity, stiffness characteristics, and deflection behavior, facilitating a systematic evaluation of both material and geometric effects. The results indicate that the GC solid slab exhibited marginally superior flexural performance compared to the OPC slab, demonstrating advantageous bond properties and material uniformity. In hollow-core slabs, elevated void ratios resulted in significant decreases in cracking load, ultimate capacity, and effective stiffness, whereas alterations in a/d caused pronounced differences in strength and deflection characteristics. Reduced shear spans improved load capacity and stiffness, while extended spans led to a more pliable load–deflection response. Analytical predictions derived from traditional flexural theory closely aligned with experimental outcomes, validating the appropriateness of classical models for GC and voided slab systems. The results show that geopolymer concrete is a structurally sound and environmentally friendly alternative to regular Portland cement (OPC). Its efficacy in both solid and hollow-core configurations facilitate its wider implementation in contemporary low-carbon structural applications.

  • Experimental and numerical investigation of the axial compressive behavior of GFRP-reinforced concrete walls under concentric and eccentric loading
    Taha A. El-Sayed, Mohamed M. Ibrahim, Ali S. Shanour, Yasser Galal Eldin Mohamed Fahmy
    Scientific Reports, 2026
    This study investigates the axial compressive behavior of reinforced concrete (RC) walls reinforced with glass fiber–reinforced polymer (GFRP) bars under concentric and eccentric loading through a combined experimental and numerical approach. The six RC wall specimens with dimensions of 1000 × 800 × 150 mm were tested and divided into two groups. For Group G1 there were three specimens tested for concentric axial loading and for Group G2 three specimens were analyzed for eccentric axial loading. One control wall in each group was reinforced with conventional steel bars and the rest were reinforced with GFRP bars in vertical and horizontal directions. The experimental program studied first-cracking and ultimate loads, cracking behavior, stress–strain response, ductility ratios, energy absorption capacity, and lateral displacements. The results indicated that replacement of steel reinforcement with GFRP bars decreased ultimate axial capacity; however, GFRP-reinforced walls maintained stable post-cracking behavior and satisfactory ductility performance. When subjected to concentrically loaded specimens, the ultimate load capacity of GFRP-reinforced walls decreased by approximately 10.8–13.3% compared with the steel-reinforced control specimen, while the ductility ratio increased by about 4.4–4.8% points. Under eccentric loading, the ultimate capacity reduction ranged from 6.5% to 14.1% relative to the steel control wall. The energy absorption capacity, assessed from the load–displacement response, was lower for GFRP-reinforced walls compared to steel-reinforced specimens; however, a stable post-cracking response was maintained under both concentric and eccentric loading. In ABAQUS, nonlinear finite element models were generated through the Concrete Damaged Plasticity (CDP) model to emulate the structural response of the tested walls, to be complementary to the experimental study. The numerical results agreed well with the experimental results regarding ultimate capacity, load–deformation behavior, stiffness degradation, and crack distribution. The deviation between experimental and numerical ultimate loads ranged from approximately 0.25% to 11.9%, confirming the reliability and acceptable predictive accuracy of the adopted numerical modeling approach. Therefore, in general, in RC wall systems it is concluded that GFRP bars present a potential viable corrosion-resistant alternative to traditional steel reinforcement. The combined experimental and numerical results yield useful information about the axial behavior of GFRP-reinforced concrete walls under concentric and eccentric loading, that can be useful for making a better design decision in future for durable and sustainable structural wall applications.
  • Structural performance of UHPC-columns reinforced with basalt bars under cyclic loading
    Taha A. El-Sayed, Muhammed S. Fekry, Hossam E. Ahmed, Ali S. Shanour
    Scientific Reports, 2026
    This study investigates the structural performance of ultra-high-performance concrete ( UHPC ) columns reinforced with basalt fiber-reinforced polymer ( BFRP ) bars under cyclic loading. Limited research has been conducted on concrete columns reinforced with basalt bars, particularly under cyclic loading conditions. In this research, six columns were cast, each with a cross-sectional dimension of 150× 150 mm and a height of 1500 mm. Each specimen was supported on a footing measuring 1000 mm in width and 250 mm in height. All specimens were tested under cyclic lateral loading until failure to evaluate their structural performance. A constant axial load of 60 kN was applied and maintained throughout the entire duration of the tests. The 28-day compressive strength of the concrete varied between 75 and 100 MPa, with mixes targeting strengths of 75, 80, and 100 MPa. Experimental results showed that columns reinforced with BFRP bars exhibited improved structural performance compared with those reinforced with conventional steel bars. The BFRP-reinforced columns demonstrated a more controlled failure mode, primarily governed by concrete crushing without reinforcement buckling, and were able to sustain higher loads with narrower crack widths, indicating enhanced deformation capacity and ductility behavior. These results confirm that despite the inherently brittle nature of BFRP reinforcement, its superior tensile strength and bond interaction with the UHPC matrix contributed to an overall improvement in cyclic stability and energy dissipation compared to traditional steel-reinforced specimens. The tensile strength of BFRP bars was nearly twice that of conventional steel reinforcement, with average values of about 1100 MPa for BFRP and approximately 500 MPa for steel. To simulate and validate the structural response of the tested UHPC columns, advanced three-dimensional finite-element models were developed using ABAQUS software. A strong correlation was observed between the numerical and experimental results in terms of initial cracking load, ultimate load capacity, crack propagation, and lateral deflection. The developed nonlinear FE models achieved approximately 85% agreement with the experimental ultimate load capacity.

  • Cyclic behavior of high-performance concrete columns reinforced with hybrid-GFRP bars
    Taha A. El-Sayed, Mohamed H. Ahmed, Ali S. Shanour
    Proceedings of the Institution of Civil Engineers Structures and Buildings, 2026
    This study examines the cyclic performance of high-performance concrete (HPC) columns with hybrid steel-glass fibre-reinforced polymer (GFRP) bars, filling a gap in existing research. Six full-scale columns were tested under axial compression (60 kN) and cyclic lateral loading, divided into two groups by bar diameter (10 mm and 12 mm). Each group included one steel-reinforced control column and two hybrid-reinforced specimens. Lateral displacement increased incrementally from ± 3 mm to ± 36 mm. Results showed hybrid columns achieved 53.24% (10 mm) and 38.27% (12 mm) higher lateral strength than controls, but exhibited reduced ductility and energy dissipation, with narrower hysteresis loops and pinching effects. Finite-element (FE) models in Abaqus software employed the concrete damaged plasticity approach to simulate material non-linearity, bond-slip and cyclic degradation, demonstrating strong agreement with experimental load–displacement behaviour and failure modes. These findings indicate that the reduced ductility of hybrid-reinforced columns may impose limitations on their seismic design applicability, emphasising the need for enhanced detailing to ensure adequate deformation capacity under earthquake loading. The study provides critical experimental data and validated modelling for hybrid-reinforced HPC systems, demonstrating their structural potential while identifying key challenges for earthquake-resistant design. The FE analysis supports its use for future parametric studies of hybrid reinforcement configurations in cyclic loading conditions.
  • Innovating rubberised eco-friendly polymer porous concrete with recycled ceramic aggregate
    Taha Awad Allah El-Sayed
    Proceedings of Institution of Civil Engineers Construction Materials, 2024
    Permeable concrete, with its porous structure, allows water to pass through easily. It is used in floors for animal facilities, sewage plant sludge beds, swimming pools, bridge walkways, and zoo areas. Eco-friendly polymers offer a sustainable alternative to traditional ones. Traditional cement concrete uses less energy and emits less carbon dioxide by utilising industrial waste instead of Portland cement. Eco-friendly polymer concrete is made through polycondensation of alkali-activated aluminosilicates like fly ash, silica fume, metakaolin, and slag. Seven concrete mixes were prepared with rubber waste replacing 5%, 10%, 15%, 20%, 25%, and 30% of coarse aggregates (dry basis). Lime powder (rich in silica/alumina) was also tested. Both fresh and hardened properties were examined. Results showed low rubber content (≤10%) had little effect on mechanical properties, but higher amounts (10%–30%) improved strength. The 15% rubber mix (M4) performed best. Rubberised geopolymer concrete works well for medium-low strength applications and reduces environmental impact by reusing rubber waste as aggregate. The material maintains good mechanical properties while providing sustainability benefits through waste utilisation. This approach helps address construction waste challenges while developing eco-friendly building materials suitable for various infrastructure projects where high strength is not critical.
  • Performance of RC Beams under Shear Loads Strengthened with Metallic and Non-Metallic Fibers
    Mona K. N. Ghali, Taha A. El-Sayed, Ahmed Salah, Nora Khater
    Buildings, 2024
    In our investigation, we subjected eleven reinforced concrete beams to a four-point bending system to explore the impact of varying fibre and ferrocement contents on their structural behaviour. These beams, measuring 1.7 m in length, featured a rectangular cross-section with dimensions of 150 mm by 300 mm. Our study focused on three key variables: steel fibre content (at levels of 0.5%, 1%, and 1.5%), glass fibre content (also at 0.5%, 1%, and 1.5%), and ferrocement content (evaluated with one or two layers of welded or expanded wire mesh). Our findings revealed that incorporating fibres with minimal shear reinforcement significantly enhanced the beams’ performance. Specifically: The specimen reinforced with 1.5% steel fibres exhibited the highest ultimate failure load, surpassing the control beam by an impressive 41.87%. The 0.5% glass fibre specimen experienced the least deflection at the ultimate load compared to the control beam. The 1.5% glass fibre specimen demonstrated superior energy absorption compared to the control specimen. Notably, using two layers of welded wire mesh proved most effective in enhancing the ultimate failure load when compared to both the control specimen and other ferrocement-strengthened beams.
