   Nyckelord :Polyvinyl chloride; PVC aggregates; natural aggregate concrete; PVC fine aggregates concrete; PVC coarse aggregates concrete;

   Sammanfattning : 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. LÄS MER
