Overview

Research demonstrates the mechanical behavior of geopolymers using red mud and soil, suggesting a viable low-carbon alternative for construction.

Key Points

  • Geopolymers stabilized by alkali activation exhibited compressive strength ranging from 2.23 MPa to 3.05 MPa, indicating their potential.
  • The study evaluated mixtures containing 70% to 100% soil and up to 30% red mud, confirming the mechanical benefits of waste incorporation.
  • Characterization of raw materials utilized tests such as X-ray diffraction to assess mineralogical changes, ensuring quality control in sustainable practices.
  • Alkali activation was shown to effectively stabilize soil and red mud mixtures, highlighting its importance for eco-friendly construction solutions.
