Physico-mechanical and durability characterization of earthen plaster stabilized with fermented rice husk for coating adobe walls
AbstractThe present study aims to study the effect of fermented rice husk (RH) on earth plaster for coating and improving the durability of adobe walls. The mixtures of clayey earthen materials and 0%, 33%, 50%, and 67% of fermented RH of the total volume of the mixture are studied to assess their p...

| description | AbstractThe present study aims to study the effect of fermented rice husk (RH) on earth plaster for coating and improving the durability of adobe walls. The mixtures of clayey earthen materials and 0%, 33%, 50%, and 67% of fermented RH of the total volume of the mixture are studied to assess their physicomechanical and durability properties. The RH is previously fermented separately in water for the periods of 2, 3, and 3 weeks. The pastes obtained after mixing the clayey earth material and fermented RH were used to mold 4 × 4 × 16 cm3 test specimens. The specimens were dried under ambient laboratory conditions [Formula: see text] and 35[Formula: see text]HR) for 21 days before their characterization. The clay earthen material mainly contains silt (51%), clay (24%), sand (23%), and gravel (3%). It has a liquidity limit, plasticity index, and methylene blue value of 32%, 20%, and 2.66, respectively. The results show that apparent density, linear shrinkage, resistance to compression, and the thermal conductivity of the plaster specimens, respectively, decrease from 1.88 to 1.07 g/cm3, 4.52 to 0.83%, 3.88 to 0.82 MPa, and 0.87 to 0.05 W/m.K with increasing volumetric content of RH from 0% to 67%. Moreover, the resistance to abrasion increased. The resistance to capillary water absorption and water erosion was deficient for the content of RH above 50%. The mixture containing up to 33% of RH allows to improve engineering performances and reaches acceptable durability and would therefore be useful for coating adobe walls. |
