Abstract

Properties of concrete containing PET plastic wastes are now well understood as a result of many experimental tests. Aspects of structural design and analysis of concrete members made from concrete containing PET waste need accurate equations for mechanical properties. In this paper, available data on mechanical properties of normal strength concrete containing PET waste were collected, analyzed, and equations were developed for calculating elastic modulus, splitting and flexural tensile strengths. Results of analysis indicate that, in general, there is a good correlation between the three properties and compressive strength of concrete containing PET plastic waste. The proposed equations were found to be safe and accurate, and can apply for recycled concrete containing different types of plastic waste other than shredded PET waste. The models proposed for mechanical properties can be utilized in the analysis and design of those structural members made from recycled concrete containing PET waste and some other plastic wastes.
