The Effect of Plaster

The resistance of aluminium in contact with plaster is excellent [11]. As in concrete, the contact with plaster leads to a very superficial and short attack of aluminium, even 

Any alteration of the surface during the setting of plaster can be avoided by protecting them with appropriate resins or lacquers. 

The adherence of aluminium to plaster is very good, twice as high as that of steel [12]. The linear expansion coefficient of plaster (25 X is very close to that of
