Experimental study of porosity and permeability of stabilized earth blocks by date palm plant fibers

The physical behavior characteristics of stabilized earth blocks (SEBs) reinforced with date palm plant fibers (PFDP) are examined in this experimental investigation. Various compounds were prepared, including 0%, 5%, and 10% lime, 0%, 5%, and 10% cement, and a combination of 5% lime and 5% cement. Additionally, fibers were incorporated at rates of 0%, 0.25%, and 0.5% by weight for each of the compounds. The study of porosity and permeability was conducted using several methods, including total porosity estimation, total volume porosity in water, open porosity, water vapor permeability, chloride ion permeability, and hydraulic conductivity, over a period of 90 days. The findings indicated that the incorporation of fiber enhanced the porosity and connectivity of pores, resulting in increased permeability of the SEBs. The cement-based bricks demonstrated a greater effectiveness than lime in decreasing the porosity and permeability of the blocks. The formulation consisting of 10% cement and the blend of 5% lime with 5% cement demonstrated satisfactory outcomes regarding porosity and permeability. This indicates that these materials are suitable for use in construction applications that demand enhanced durability and resistance to both natural and chemical influences.
