As an illustration, according to the Chinese Water Resources Professional Standard SL 282-2003 [2], physical model is only used as a recommendation for first-grade and second-grade structures or structures that are especial in the construction process so as to verify the numerical model, while the FEM is used for stress analysis of arch dams.
The Vietnamese Water Resources Professional Standard 14TCN 56-88 [5] has specified that for arch dams with a height greater than 60m or below but relatively under complex conditions of structure or foundation, stress analyses must be performed based on both numerical and physical testing models, additionally designers are optional to select an analysis method to the numerical model.

Main slag components are: § gehlenite - 2CaO.Al2O3.SiO2 § akermanite - 2CaO.MgO.2SiO2 § melilite - solidified gehlenite and akermanite solution § merwinite - 3CaO.MgO.2SiO2 § belite - β - 2CaO.SiO2 § wollastonite - β - CaO.SiO2 By its properties the granulated blast furnace slag is classified among so called latently hydraulic materials, i.e. materials that after adding of water do not mature or solidify.
During their hardening compounds similar to compounds formed at slag-Portland hardening are formed. [1] They are characterised with small development of hydration heat and significant resistance to aggressive waters.
· normal consistency; performed by Vicat method · compressive strength and tensile strength at bend; they were set with hydrated pastes with water - binder ratio corresponding to a normal consistency mash.
At theoretical study of professional literature (3) they obtained compressive strengths and ability to resist aggressive environment effects were emphasised, however also the questions of slag binding capacity loss and disintegration were mentioned in dependence on amount and type of used exciters and contained impurities which are perceptible only after a longer period of hydration.
