[Greenbuilding] crushed brick

[Gennaro Brooks-Church - Eco Brooklyn]

Yes these bricks are a hundred years old and definitely the low temp fired
type. I suspected as much.
So....expanded shale would be wonderful but has high embodied energy, lava
rock would be wonderful but NY has few volcanoes, pumice floats, the 100
year old salvaged Spanish style tile may have lead sealer.....which brings
me back to gravel - which does not have as high a surface are by far but
sure is easy to come by in NYC....
