Re: density of hollow tile blocks

[Ted de Castro <tdc@xrayted.com>]

I've had to do this before.

Simply weigh one!!  You have the area.  If you really want to get picky
- break one and weigh the thin part and ignore the thicker part - that
would be the conservative estimate.

I felt as a secondary barrier this simpler method was enough.

Of course - once it is weighed - it is just concrete - but lower
density.
