Improvement of Concrete Characterization Using Nanomaterials: State‐of‐the‐Art

Journal of Engineering, Volume 2025, Issue 1, 2025.
The utilization of nanomaterials in concrete has undergone extensive research to enhance its properties. Nanosilica (NS), nanoalumina, nanometakaolin (NMK), nanoclay (NC), and nanocarbon dioxide have demonstrated the ability to improve the compressive strength of concrete at different ages, with a more pronounced impact on early strength.

Effect of CFRP Sheets Strengthening Method on Behaviour of Modified Lightweight Foamed Concrete Beams

Journal of Engineering, Volume 2024, Issue 1, 2024.
This study has been adopted to examine the effect of carbon fibre‐reinforced polymer (CFRP) sheet strengthening methods on the flexural behaviour of modified foamed concrete beams reinforced with different steel reinforcement ratios, and it deals with the enhancement in flexural behaviour of conventional nonstrengthened FC beams. Twelve modified foamed
