@All.

As I know, A good building stone should not absorb more than 15% of water. But, there is mentioned that a good stone should not absorb water more than 10%.

That means according to your site a stone having 11% absorption of water is not a good building stone.

Am I right? Anyone, clarify me.

A good building stone should be less porous. It should not absorb more than 5% of water. Any stone absorbing 10% of water should be rejected.

For good building stone I mean stone used in the building should not absorb water than 5% and for just stone, it's 10%.

Water absorption is not more than 15% and Porosity should not be more than 5%.

5% water absorbed is a good quality stone so more than 5% water absorbed are rejected.

Some books show the answer as 15%.

Which is the correct answer? Please tell me.
