The soil that particle diameter is greater than 0.075mm and the mass ratio is more than 50% is defined as coarse-grained soil by the corps of engineers, bureau of reclamation and society for testing materials [1].
With the improvement of design ability, construction technology and material test level in water resources and hydropower engineering, the limitation to dam materials have more breakthroughs and relaxation.
Under the condition of fine content P5≧30%, when the fines content P5 increases, the pore between the coarse material is filled with fine material, even some of the coarse material is distracted by fine material.

Gibson summarized the use of the modal vibration response measurements to characterise the mechanical properties of fibre reinforced composite materials and structures [2,3] and also affirmed that modal testing by impulse excitation method is a fast and accurate approach to characterise the global elastic constants of composite material.

Some researchers [37-38] through studying on the new ventilation unit of the phase change material, have found that the phase change material,whose physical properties changing with temperature, can make the façade cavity absorb waste heat during the day while not cause overheating and it can be used as a pre-cooling and cold storage device during the night, providing a high energy saving efficiency.

In this approach, neither adding nor removing materials.
In some cases, powder or sheets materials are used to replace that of liquid.
Main limit is that the materials can be synthesized again by solution.
In this case, the most materials can be processed.

The project is informed by a centuries-old evolution of formwork/falsework for plastic building materials (concrete, etc.), which have steadily become animated (fig. 2).
This particular machine is targeted for these regions, and materials 5. studies that correspond to this formwork’s development include liquefied mud with organic fiber reinforcement, and/or a liquefied mud-cement mixture. 6.
Model 5 used a “soft gasket” to prevent liquid/plastic materials from escaping through gaps in the linked cartridges without compromising the flexibility and variability of the formwork.
In addition to materials testing, an additional component of this project’s development will be writing a “design program” or app based upon the basic rotational commands that move one cartridge in sequential relation to one another.
