Rock Salt and #10 concrete. Some I made in a sand form others I made free hand. It is in a bucket outside curing right now.

I made about 6 pieces so far. Hopefully more this weekend. If anyone has any ideas on how to easily crush water softener salt please let me kow. The pieces of salt are tooo big for the rocks I am making, so I had to use a hammer last time.

Interesting.

What is the purpose of the rock salt?

How are you going to lower the Ph of the cement?

You didn't use any aragonite sand at all?

The rock salt creates holes in the concrete giving it light weight and ?porosity?

I didn't use the sand cause I didn't like the looks of it. Right now the "rocks" are still very grey but will lighten up in time. I will post a picture of one of the pieces tonight.

As far as the ph goes, concrete once cured (6 - 8 weeks) will lose its high ph content. You just soak it in fresh water with water changes every day or 2.

Cool idea for making the rocks more porous.

It doesn't matter what color the rocks are, they will get covered in coralline algae anyways.

Very true. So now the next thing I need to find is a source for course rock salt in town.
