LIGHTWEIGHT CONCRETE MADE WITH WASTE EXPANDED POLYPROPYLENE-BASED AGGREGATE AND SYNTHETIC COAGULATED AMORPHOUS SILICA
Recycled plastic aggregate can be used as an alternative material to produce lightweight concrete with low environmental impact. Polypropylene is one of the least recycled post-consumer plastics. In the present study we focused at waste expanded polypropylene (EPP) aggregate that is used for partial replacement of natural aggregate to produce lightweight cementbased composites. Coagulated silica was used as admixture for improvement of dispersion of EPP particles in the cementbased matrix. Atdoi:10.13168/cs.2018.0015 fatcat:mxb5flumebbk3ltg4he3cdsdu4
