A Latest research paper titled “Performance Evaluation of Cohesionless Soils Stabilized Using Metakaolin-Based Geopolymer for Infrastructure Applications” has been published in the prestigious “Journal of Materials in Civil Engineering.” Authored by Oscar D. Huang, Dr. Jungyeon (JayJay) Jang, Dr. Surya S C Congress, Dr. Anand Puppala, and Dr. Miladin Radovic, this study offers insights into the use of geopolymers as an effective and sustainable solution for enhancing cohesionless soils commonly found in coastal areas. The study demonstrates that metakaolin-based Geopolymers (GPs) are not only eco-friendly due to their low carbon footprint, but they also significantly improve the Unconfined Compressive Strength (UCS) and resilient modulus of cohesionless soils. Our tests showed a 115 times increase in UCS after only 3-day curing with 20 wt.% GP. The results from this research present new opportunities for sustainable construction practices, especially in areas requiring the stabilization of weak cohesionless geomaterials.
