Implication

This study evaluates the geotechnical effectiveness of coffee husk ash as a soil stabilizer, showing significant improvements in clay soil properties.

Key Points

Inclusion of coffee husk ash significantly increased the ultimate compressive strength from 89.17 kN/m² to 130.83 kN/m².
The study found that coffee husk ash enhances both the mechanical and physical characteristics of clay soil.
Testing showed improved soil cohesion and internal friction angles alongside the addition of coffee husk ash.
Laboratory testing varied coffee husk ash content from 5% to 25%, revealing a positive impact on soil stability.
