Construction material by using the sediment is realized of making waste profitable.
The features of this technology are listed as follows: (1) the application of usable materials has greatly lowered the product cost; (2) the solidified sediment product has good leakage resistance and is the ideal material used in the irrigation and water conservancy engineering; (3) the technology is simple for mechanization manufacturing and the product quality is quite reliable; (4) the manufacturing process of solidification is free from sintering.
Materials (1) Material and its features The raw material is the sediment and it is taken from the Yanglanhe Reservoir in the Wangzhuang irrigation district, south of Hekou, Dongying city.

The applied magnetic field could promote the refining degree of crystallization, decrease impurity in the deposited materials, and change the distribution of hard phase.
So far, the recent researches mainly focused on the effects of the magnetic field parameters on the property of the deposited materials, and less attention had been paid on the interaction mechanism between magnetic field and metallic materials during welding.
Reference [9] suggests that for materials with the magnetic anisotropy, the magnetic moment vL under the steady magnetic field can be expressed as θ χ 2sin 2 1 2 VHLv ∆=
