A Study on Eco Friendly Cost Effective Earthbag House Construction

The weakest specimens showed maximum compressive strengths ranging from 115 kN/m to 135 kN/m. The lowest load deformation response was observed for the Gf 9 specimen group, at 0.7 kN/mm. The strongest and stiffest results were observed for the 3-bag soil-filled specimen, with load deformation responses ranging from 8 kN/mm to 15 kN/mm, and compressive strength ranging from 1100 kN/m to 1300 kN/m. Strength and stiffness values for medium soil-filled specimens measuring 510 mm x 910 mm were in the same range as the values for the small specimens. There was little difference in stiffness between specimens filled with topsoil and those filled with a 4:1 ratio of topsoil to masonry sand, though small sample size prevents a meaningful statistical analysis of the variance between the two fill materials. Beyond material properties, climatic conditions must also be considered to ensure optimal selection of building materials.
