Initial analysis of the influence about manufacturing methods on forming quality of similar material specimen

Abstract

By comparing the physical and mechanical properties of the similar materials made from the same material making method and the same making method, the influence of different factors on the quality of the specimen is analyzed from the three aspects of the apparent density, the compressive strength and the modulus of elasticity of the similar materials. The test shows that the uniformity of apparent density does not relate to the uniformity and density of the specimen itself, but the control of the quality and size of the single specimen can help to reduce the difference between the specimens. The quality of the die is better than the cylindrical mold; the one-time loading is easier to obtain the less fluctuation of the compressive strength and the modulus of elasticity. And the machine compacted specimen has better molding quality.
