Abstract

Plastics are low cost, lightweight, and many uses material. As result, increase in plastic led to the environmental pollution. So, this incited the researchers to use the plastic in concrete to produce sustainable concrete. In this paper, experimental work was presented to investigate the behavior of columns with and without waste fibers polyethylene terephthalate under axial load. These columns were divided into three groups depended on ratio of fiber 0%, 0.5%, and 1% and configuration of steel bars. Some mechanical properties of concrete were tested. Main results obtained fiber inclusion resulted in an improvement in splitting and a decrease in compressive strength. Results also showed an improvement in crack load for columns when adding fiber, which reached the highest percentage about 45.79%.
