If rust is porous that means that water can pass through it. This means that when the surface of a metal rusts it 'exposes' fresh metal underneath to water, meaning that that rusts too.In short, rust being porous means that all the metal is effected not just the surface.
When Aluminium rusts it forms a hermetic (waterproof) layer which actually prevents further damage. That is why aluminum does not have to be as heavily protected as iron (which should be painted or galvanised to waterproof it)

Does metamorphism make the rock more porous or less porous?
more porous
Is a concrete non porous?

Which prevents the resources of Antartica from being used?

How do you make concrete non porous?
To make concrete non-porous, you can add a waterproofing admixture during the mixing process. This helps to reduce the absorption of water into the concrete, making it less porous and more resistant to water penetration. Additionally, you can seal the surface of the concrete with a waterproof sealer to further enhance its non-porous properties.
What porous object?
* able to absorb fluids; "the partly porous walls of our digestive system"; "compactin the soil to make it less porous" * full of pores or vessels or holes == ==
Are steel porous or non-porous?
Steel is typically considered non-porous due to its dense and solid structure. However, certain types of steel can have micro-pores or surface imperfections that make them slightly porous. Generally, stainless steel has better resistance to corrosion and is less porous than other types of steel.
What are the advantages of expensive clothing?
You can have it cleaned over and over without damaging it. If it is expensive, there are many events to which it can be worn; also, you probably will receive many compliments.
