Effect of Polyethylene Terephthalate (PET) in Development of Green Roller Compacted Concrete

This paper aims to find out the possibility of development Green Roller-Compacted Concrete (RCC) by using local materials and study the behavior of RCC properties by adding different amounts of solid waste (Polyethylene Terephthalate (PET) as volume fraction of cement content). To achieve this aims; Three laboratory tests were applied; Density, Compressive strength, and Flexural strength, that conducted to show the changes in the properties of concrete with existence of PET in the mixture. an approach for adding the PET in the concrete mixture. ranging from 1.0 % to 3.0 % with the variation of 1.0 %. Therefore, Three concrete mixtures was prepared to study the affect of adding (1.0 – 3.0 ) % of PET as volume fraction of cement content. On the other hand, one additional mixture designed without any inclusion of PET to be considered as a reference mixture. It can be observed in general from of the results that the increase in the percentage of Polyethylene Terephthalate (PET) in the mix leads to decrease in the compressive strength to 15 %. Results show that The use of Polyethylene Terephthalate (PET) would enhance the flexural strength of LWAC to 69.4 %.
