Relevance Along with conventional roll materials, torch-welded waterproofing can be used for the protection of concrete surfaces from the destructive effect of corrosive groundwater and the prevention of capillary moisture penetration.
These materials are used on horizontal and vertical surfaces of hydraulic facilities, they have high structural characteristics, increased adhesion to concrete, and resistance to ultraviolet radiation.
Theoretical Part Like the other materials, liquid rubber has certain advantages and disad-vantages, given in Table 2.

One of the most interesting materials is ceramic because of its hardness, of its relatively small density and of the reduction of collateral damages, and the other one of the most interesting materials is aluminum because of its small density and ductility.
Clear correlations are observed between the projection capability and the confinement materials.
In this paper, we shall compare results obtained by varying the materials of the confinement plates made of steel, ceramics, aluminum and copper.
MATERIALS USED One steel alloys, one aluminum, one copper and one ceramic have been selected to investigate the behavior of the RACs.
Table 1 lists these materials their properties.

The merging layer adopted heteropic gradient material, and which was compounded with two or more materials.
But they all didn't consider mutual effect among Ingredient materials, and the results were inaccurate.
On the other hand, low-melting welding powder is a kind of composite material and coefficients of heat expansion of various materials in welding powder are inconsistent.
