Materials Characterization and Compressive Strength of Compressed Earth Blocks Reinforced with Oat Straw
This paper describes the material characterization, compressive strength, and chemical composition of two compressed earth blocks (CEBs) stabilized with oat straw. The properties of the oat straw and soils used for the improvement of the CEBs were evaluated. The compressive strength was assessed by randomly choosing and testing 26 pieces. In addition, the chemical composition was obtained. As a result, the unit density of the oat straw is within the top limit of the experimental referenced values; however, the absorption records the highest value, i.e., one outside of the experimental referenced range. The soil properties are within the ranges defined by international standards. The compressive strength is adequate for both pieces (2.9 MPa for CEB A and 4.7 MPa for CEB B), but the initial absorption is high. Silica and calcium oxide comprise 90% of the chemical composition of the two pieces. Considering the high absorption of these CEBs, their colocation is not recommendable in the lower parts of walls. This is to avoid standing water in the foundation soil. The highest compressive strength of CEB B is related to the plastic index and chemical composition.
