    • Effect of self-healing calcium nitrate microcapsules on concrete properties 

      Milla, Jose; Hassan, Marwa M.; Rupnow, Tyson; Al-Ansari, Mohamed; Arce, Gabriel ( National Research Council , 2016 , Article)
      Self-healing concrete with microencapsulated calcium nitrate was investigated. The compressive strength of concrete admixed with microcapsules (as a percentage of the weight of the cement) was tested and compared with that ...

    • Microencapsulation of calcium nitrate for concrete applications 

      Hassan, Marwa M.; Milla, Jose; Rupnow, Tyson; Al-Ansari, Mohamed; Daly, William H. ( National Research Council , 2016 , Article)
      The use of encapsulating healing agents that allow the self-healing of concrete has emerged as a potential solution to the current decay and costly maintenance of concrete infrastructure; however, many healing agents are ...

    • Optimum Dispersion Parameters of Carbon Nanotubes: Concrete Strength by Response Surface Methodologies 

      Mohsen, Mohamed; Al Ansari, Mohamed; Taha, Ramzi; Senouci, Ahmed; AbuTaqa, Ala ( Qatar Univesrity Press , 2020 , Conference)
      "This paper implements Response Surface Methodologies (RSM) techniques to illustrate the maximum carbon nanotubes (CNTs)-concrete mechanical properties responses to the length, weight fraction and treatment variables. ...
