Effect of mix proportion on the strength and durability of plastic and ...
6 days agoThe result indicated that the flexural strength increases as the content of sand in the composite increases. Waste PET plastic and sand composite at mix ratio 1:3 showed significantly higher values of 39% and 21% than mix ratios 1:1 and 1:2, respectively. The sand tends to reinforce the composite and thereby enhancing its resistance to bending.
