Cement Recipe? Building Lightweight Growing Benches
I want to make growing benches out of concrete and cinder blocks.
(Stop me here if this is the wrong approach.) Everything made of wood will rot here in New Orleans. I want to make bench tops about 18inches deep and 30inches wide and 1.5 inches thick. I'll use cinder blocks to support the bench tops. Problem is that I don't think that Quickcrete is the right mix for the job. The gravel is too large and the result is too heavy. So I want to mix my own. I figure the Gravel is the only component I can change to make the concrete lighter. Any suggestions on what I should do here? Bill. |

Cellular concrete is done in this way. alain -- http://brezhonegbev.free.fr Brezhoneg ar vro vigoudenn war ar rouedad |
