Effect of Introducing Recycled Polymer Aggregate on the Properties of C-PC Composites
The subject of this paper is the evaluation of possibility of using the plastic waste fillers as the coarse aggregate of two Concrete-Polymer Composites (C-PC): polymer-cement concrete (PCC) and polymer concrete (PC). The applied fillers were crushed high density polypropylene (HDPP) wastes remaining after grinding plastic elements used in mountings and thermal insulation systems. The substitution of natural mineral coarse aggregate (river gravel) with plastic material was done on the various levels (0 ÷ 40% in case of PCC and 0 ÷ 100% in case of PC). For all composites the density, flexural strength and compressive strength were determined and compared with those for reference composites containing only the river gravel. The results enabled to indicate the levels of possible substitution of the natural aggregate, the non-renewable resource, with waste material, so that the properties of C-PC remain at the satisfactory level.
