    • 3D-Printed Clay Enhanced with Graphene Nanoplatelets for Sustainable and Green Construction 

      Mohsen, Mohamed O.; Al-Diseet, Malak M.; Aburumman, Mervat O.; Taha, Ramzi; Taqa, Ala Abu; ... more authors ( Multidisciplinary Digital Publishing Institute (MDPI) , 2023 , Article)
      This paper presents a study on the effects of graphene nanoplatelets (GNPs) on the mechanical behavior of 3D-printed burnt clay, the most sustainable and green construction material, under constant printing parameters. ...

    • Effect of using Cement Kiln Dust as a nano-material on the strength of cement mortars 

      Alnahhal, Wael; Taha, Ramzi; Al-Nasseri, Hammad; Nishad, Safna ( Springer Verlag , 2017 , Article)
      In this experimental study, the effects of using nano-sized Cement Kiln Dust (CKD) as a partial replacement for Ordinary Portland Cement (OPC) on the strength of cement mortars is investigated. The CKD was milled up to 4 ...

    • Evaluation of Combined Excavation Waste and Reclaimed Asphalt Pavement Aggregates for Use in Road Bases and Sub-bases 

      Taha, Ramzi; Sirin, Okan; Sadek, Husam ( OMICS International , 2014 , Article)
      More than 15 million tons of aggregates are imported each year to Qatar from neighbouring countries. Large quantities of waste materials (around 20 million tons/year) from excavation waste, demolition rubble and reclaimed ...

    • Recycling of Local Qatar’s Steel Slag and Gravel Deposits in Road Construction 

      Taha, Ramzi; Sirin, Okan; Sadek, Husam ( OMICS International , 2014 , Article)
      Every year, the State of Qatar generates about 400,000 tons of steel slag and another 500,000 tons of gravel as a result of steel manufacturing and washing sand, respectively. The two materials (by-products) are not fully ...

    • Use Of Cement By-Pass Dust In Soil Stabilization 

      Taha, Ramzi; Al-Rawas, Amer; Al-Harthy, Ali; Al-Siyabi, Hilal ( Qatar University , 2001 , Article)
      Cement by-pass dust (CBPD) or cement kiln dust (CKD) is a by-product of the manufacture of Portland cement. It is generated during the calcining process in the kiln. Lime (CaO) constitutes more than 60% of CBPD composition. ...

    • Use of local discarded materials in concrete 

      Taha, Ramzi; Al-Nuaimi, Nasser; Kilayli, Abdulazeez; Salem, Abdelhamid Ben ( 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 ...
