Abstract
The aim of this study is to investigate the efficiency of using green ultra-high-performance concrete (GUHPC) with corrosion resistant alloy steel (MMFX) Bars in overcoming concrete cracking and steel corrosion, which will help in reducing inspection, maintenance, and repair works. To do so, a nonlinear finite element (FE) analysis was carried-out to model full-scale concrete beams which are often subjected to cracks during its service life time. The obtained results were compared with experimental data and the comparison was most satisfactory. In addition, a comparison was made between the proposed materials and traditional reinforced concrete in terms of crack widths, the intensity of cracks and service life period. The obtained results showed that using GUHPC and MMFX as a construction material in concrete structures provides high stiffness, high strength, enhanced service life and crack control beside its cost efficiency.
