STUDY OF THE PROPERTIES OF MORTAR INCORPORATED FROM MELTED PLASTIC BAGS

The aim of this research is to study the physical-mechanical behaviour and durability of mortars containing melted plastic bags. To this end, 4cmx4cmx16cm test specimens of mortar containing cement or not and melted plastic bags at a mass ratio ranging from 10 to 25% of the mixture were produced. Compressive strength, flexural strength and acid durability were measured. The results show that the quantity of plastics in the mortars is inversely proportional to water absorption. Similarly, cementless mortars containing 25% plastic bags (MWC25) and cement mortars containing 25% plastic bags (CM25) gave maximum compressive strengths of 9.45MPa and 10.45MPa respectively. The durability test in a 5% sulphuric acid solution showed that CM25 and MWC20 lost 50% of their mass after 28 days.
