Bond characteristics of different FRCM systems
( Elsevier , 2018 , Article)© 2018 Elsevier Ltd Fabric-reinforced cementitious matrix (FRCM) composites are usually applied on the concrete surface for the purpose of strengthening reinforced concrete structures. The efficiency of FRCM as a strengthening ... -
Effect of carbon nanotubes on the bonding mechanism of non-corrosive reinforcements to concrete
( Elsevier , 2024 , Article)This study aimed to assess the impact of waterborne pre-dispersed multiwall carbon nanotubes (MWCNTs) at a concentration of 0.2 wt % on the bond strength between concrete and non-corrosive reinforcements, including stainless ... -
Evaluation of Bond Strength Between Carbon Fiber Reinforced Polymer (CFRP) Composites with Modified Epoxy Resins and Concrete
( Qatar Univesrity Press , 2020 , Conference Paper)Rehabilitation and strengthening of concrete structures are becoming more significant in civil engineering applications. The use of externally bonded Fiber Reinforced Polymers (FRP) is one of the methods to strengthen and ... -
Numerical simulation of the fracture and compression response of self-healing concrete containing engineered aggregates
( Elsevier , 2023 , Article)The existing self-healing concretes that rely on capsules require modifications to one or more traditional concrete mixing, placing, and consolidating methods. Additionally, concrete mixture designs need alterations to ... -
Performance of modified self-healing concrete with calcium nitrate microencapsulation
( Elsevier Ltd , 2017 , Article)This study investigates the strength reduction associated with incorporating calcium nitrate microcapsules in concrete. It also proposes modifications to the calcium nitrate micro encapsulation procedure to minimize the ... -
Use of local discarded materials in concrete
( Elsevier , 2014 , Article)Steel slag, a by-product of steel manufacturing, is generated in large quantities in Qatar. In fact, it is estimated that more than 400,000tons of steel slag are generated annually in the country. Gravel, resulting from ...
