Influence of content and particle size of waste pet bottles on concrete behavior at different w/c ratios. Albano C, Camacho N, Hernandez M, Matheus A, Gutiérrez A. This study evaluates the effect of waste polyethylene terephthalate (PET) granules on the fresh, mechanical and absorption characteristics of self-consolidating concretes (SCCs). Fine aggregates were replaced with different percentages (from 0% to 8%) of PET granules obtained by crushing waste PET bottles.

Byung-Wan, Jo, Seung-Kook, Park, Jong-Chil, Park, Mechanical properties of polymer concrete made with recycled PET and recycled concrete aggregates. Self-compacting concrete (SCC) is a special type of concrete which can be placed and consolidated under its own weight without any vibration effort due to its excellent deformability, and which at the same time is cohesive enough to be handled without segregation or bleeding.The concept of SCC was first proposed by Okamura in 1986, and the prototype was first developed by Ozawa at the University of Tokyo in 1988 [1,2] . The combined effects of waste Polyethylene Terephthalate (PET) particles and pozzolanic materials on the properties of self-compacting concrete. Properties and durability of concrete containing polymeric wastes (tyre rubber and polyethylene terephthalate bottles): An overview.
