The experimental program contains testing of 12 RC beams divided into three groups; the first and second group consists of four beams tested until failure in bending with bottom reinforcement ratio of 0.837% and 1.88 % respectively, while the third one consists of four beams tested until shear failure was reached. Each group consists of one control beam, one beam with 3% of nano-SiO<sub>2</sub>, one beam with 1% of nano-Al<sub>2</sub>O<sub>3</sub>, and one beam with 1% of nano-TiO<sub>2</sub>. Based on the analysis of experimental data, it was concluded that the addition of nanoparticles, mainly nano-Al<sub>2</sub>O<sub>3</sub>, to the concrete mixtures can lead to a flexural strength increase but using 1% nano- TiO<sub>2</sub> addition is more effective to enhancement the beam shear strength.</p&gt;}, number={3s}, journal={International Journal of Advanced Science and Technology}, author={Gabr, Ahmed Shaban Abdel-Hay}, year={2020}, month={Mar.}, pages={884 - 896} }
