Earth building is a traditional architectural form. With respect to environment protection, low cost, convenient advantages, its practical value is recognizing carefully. Due to poor mechanical properties and durability of earth, the development of earth building has been prevented. This experiment selects two kinds of soil. Sawdust and straw serve as admixture. More than 300 specimens have been performed to verify the effects of various factors on soil’s physical and mechanical characteristics. Some useful characteristics are acquired by the experiment, such as soil’s optimal moisture content, maximum dry density, optimal length of straw and contraction ratio. Testing the influence of admixture on soil’s strength and deformation, this experiment shows that mixing straw and sawdust reduce soil’s compressive and tensile strength. However, it may reduce soil’s contraction ratio. Considering the influence of admixture on soil’s contraction and strength, when soil 1 mixes with 0.1% sawdust, its contraction ra...
