Experimental study shows rice husk enhances hygrothermal and mechanical properties of adobe bricks, suggesting benefits for sustainable building materials.
Key Points
Hygrothermal performance improved significantly; thermal conductivity reduced by up to 35% for calcareous soil at 3 wt%.
Mechanical enhancements varied by soil type; siliceous soil showed increased strength at 1 wt%, while calcareous only at 3 wt%.
Acoustic properties remained low, highlighting limited gains in sound insulation due to macro-porosity.
Soil composition critically influences effectiveness of rice husk in stabilizing adobe bricks, suggesting tailored approaches.
