The determination of the suitability of local soil in the production of stabilized compressive interlocking earth block

Project Abstract

The construction industry is increasingly seeking sustainable and environmentally friendly building materials. One such material that has gained attention is the stabilized compressive interlocking earth block (SCIEB). This study focuses on the determination of the suitability of local soil for the production of SCIEBs. The research methodology involved soil sampling from different locations to evaluate their physical and chemical properties. Tests such as sieve analysis, Atterberg limits, and X-ray diffraction were conducted to understand the soil composition and characteristics. Additionally, stabilization techniques using cement and lime were employed to determine the optimal mix ratios for enhancing the strength and durability of the blocks. The study found that local soil samples exhibited varying properties, with differences in particle size distribution, plasticity, and mineral composition. Through stabilization with cement and lime, the compressive strength of the blocks was significantly improved. The optimal mix ratio of soil, cement, and lime was established to achieve the desired strength while maintaining the interlocking properties of the blocks. Furthermore, the study assessed the environmental impact of using SCIEBs compared to traditional fired bricks. Life cycle assessment (LCA) was performed to analyze the carbon footprint and energy consumption throughout the production process. The results indicated that SCIEBs have lower embodied energy and carbon emissions, making them a more sustainable alternative to conventional bricks. In conclusion, the research demonstrates the feasibility of utilizing local soil resources for the production of stabilized compressive interlocking earth blocks. By understanding the soil properties and applying appropriate stabilization techniques, it is possible to manufacture blocks with improved strength and durability. The environmental assessment also highlights the benefits of SCIEBs in reducing the overall environmental impact of construction activities. This study contributes to the ongoing efforts in promoting sustainable construction practices by utilizing locally available materials and reducing the reliance on energy-intensive building products. The findings provide valuable insights for architects, engineers, and policymakers in adopting eco-friendly building solutions using stabilized earth blocks. Further research could explore alternative stabilization methods or investigate the long-term performance of SCIEBs in actual construction projects.
