Microstructure, Physical and Mechanical Properties of Adobes Stabilized with Rice Husks
The main objective of this study was to manufacture resistant, durable adobes having low thermal conductivity. For this purpose, a moderately plastic clayey soil from Korsimoro (Burkina Faso) was used to manufacture adobes reinforced with up to 1 wt.% of rice husks. The chemical and microstructural characteristics of the rice husks were evaluated, as were the physical, mechanical and microstructural characteristics of the adobes that were manufactured. The incorporation of rice husks in the clayey matrix increased the compressive strength of adobes and decreased their thermal conductivity. From a durability point of view, the addition of rice husks in adobes decreases the capillary absorption and improves the resistance to water erosion, due to the good adhesion of rice husks with the clayey matrix. According to standards related to building materials, adobes manufactured with at most 0.4 wt.% are suitable for the construction of resistant and durable dwellings that provide acceptable thermal comfort.
