Do protective coatings add strength? (e.g. If you soaked the lightweight concrete with thinned acrylic paint & then an outer coating of water based/ acrylic polyurethane, for example)?
I don't understand the reasoning of this. You often say concrete is like a sponge, absorbing water. If I make a lightweight sculpture of cement & vermiculite, for example, it would be even more like a sponge, due to the absorbency of vermiculite. If I tried to pinch off a piece of a sponge, it comes off very easy. But if I soak that sponge in some acrylic polymer/ paint, even watered down some (according to Golden Paint company/ Just Paint articles some adhesion property still exists all the way to a 20:1 dilution of water to acrylic), the acrylic still retains adhesion properties & after drying in the "sponge," it would make it much tougher to pinch off a piece of the sponge. Your sponge would no longer be soft, but now firmer, harder, with the particles held together with more adhesion, making it much harder to pinch off a piece.. So why would you reason that would not make an indoor, lightweight sculpture, such as with vermiculite, a bit less fragile, such as to abrasion of being bumped or rubbed against, so pieces won't as easily abrade off? I'm curious to get your sense of this, as I was planning to do a process along this line, for a lightweight indoor sculpture (probably with a wire armature, admixtures, fibers as well), & prefer to get things right as much as possible from the beginning. @@creatingconcrete
It is not the absorbing of water that damages concrete, it is the water passing through the concrete which erodes it over time. Vermiculite holds water. So it is like a sponge, and will make concrete damp for much longer than if there were no vermiculite in it. It does not harm the concrete to have absorbent verm in there.@@cchemmes-seeseeart3948
Thank you for this enlightened knowledge
Why not use plastic netting inside ?
How about LW concrete for a garden bed? Would it bee too weak?
If i create clc block , by adding fibers , is that safe for walls against cracks?
If i put clc in water for 2-5 days , how much effective?

I do not believe this would add any appreciable strength.
