Optimization of polyethylene teraphtalate [sic] terephthalate content in mortar using Taguchi method

Abstract

This study aimed to investigate the impact of PET (polyethylene terephthalate) content in concrete mixes, specifically in mortar, and to optimize the mix using the Taguchi method. Nine mixes, including PET and additives such as SBR-Latex, were examined, along with three control mixes. The effects of these materials on the workability and hardened properties of the mortar, including flexural and compressive strength and water absorption, were studied. The results revealed that the addition of PET to the mix increased workability, an essential characteristic for ensuring easy handling and application of the mortar. However, the hardened properties of the mortar, such as flexural and compressive strength and water absorption, were decreased. To address these limitations, SBR was added to the mix, which improved the performance of the mortar. Overall, this study highlights the potential benefits and drawbacks of using PET in mortar and suggests that the inclusion of SBR may help overcome some of this material's limitations. The Taguchi method was used to optimize the mix, which allowed for a more efficient and effective approach to evaluating the impact of different materials on the mortar's properties. These findings may be valuable for researchers and professionals in the construction industry seeking to improve the performance and durability of mortar mixes.
