Abstract：
In order to study the mechanical properties of miconcrete which was the similar material mode of reinforced concrete structure，the mechanical property of miconcrete mixed by different content of aggregate and ceramsite under static loadings are investigated through experiments. The constitutive model, relationship between elastic modulus and strength, the influence of aggregate mechanical characteristics of general concrete in the elastic and inelastic stage. When the demand of modulus of elasticity met under the condition of aggregate and ceramsite mixed，of the structure model is closer to the actual structure，and the scale mode of large structures the weight of structure model was increased and clump weigh was reduced. The mass distribution in the small shaking table is achieved.
