  3. 2. Use of Polyvinyl chloride (PVC) as an aggregate for concrete

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Habib Loubani; [2023]
    Keywords : Polyvinyl chloride; PVC aggregates; natural aggregate concrete; PVC fine aggregates concrete; PVC coarse aggregates concrete;

    Abstract : This study investigates the use of polyvinyl chloride (PVC) as a partial substitute of natural aggregates in concrete as fine and coarse aggregates. Concrete was prepared by replacing natural aggregates with equal volume of grinded PVC, with volume replacement ratio as 10%, 50% for fine and then 10% and 50% for coarse aggregates. READ MORE

  6. 5. Impacts of Using Crushed Rocks in Concrete.

    University essay from KTH/Teknisk geologi och geofysik

    Author : Andre Horta; [2011]
    Keywords : Crushed rocks; Mortar rheology; Fresh concrete workability; Cement content; Superplasticizer; Filler;

    Abstract : Concrete in Sweden has traditionally been manufactured with natural aggregate from glaciofluvial eskers. There is a need to preserve the remaining eskers because of their cultural value and importance for water filtration, thus natural aggregate has to be replaced. The most realistic alternative is to use crushed rocks. READ MORE
