Influence of Polymer on the Unconfined Compressive Strength of Peat-Polymer Mixtures

Abstract

This study investigates the influence of polymer on the unconfined compressive strength of peat-polymer mixtures. Peat soil is known for its low strength and high compressibility, making it challenging for various engineering applications. To improve its mechanical properties, polymers Vinyl Acetate - Acrylic Copolymer (VAAC) were added to peat soil as stabilizing agents. The objective of this research is to assess the effect of polymer content on the unconfined compressive strength of peat-polymer mixtures. Laboratory testing is conducted on samples that cured for 1,3,5 and 7 days and the compressive strength of the peat polymer mixtures were measured using unconfined compression tests. The results demonstrate that the addition of polymers significantly enhances the compressive strength of the peat-polymer mixtures. As the polymer content increases, the compressive strength of the mixtures exhibits a substantial improvement. The findings of this study provide valuable insights into the potential of polymers as effective stabilizing agents for peat soil, offering potential solutions for enhancing the engineering properties and performance of peat-based construction materials.
