[Greenbuilding] bio bricks?

I wonder if this technique could include reinforcing to replace concrete, such as concrete panels like superior wall?  I am aware that concrete is high co2.

This reminds me of some of the ancient techniques for making earthen floors; bacteria, anaerobic conditions etc..

Beginning with sand, a liquid mixture of bacteria, nitrogen, food for the bacteria, a calcium source, and water are added.  Over 5 days, the liquid is gradually added until the food and water run out and the sand dries.  At that point, it is a concrete brick, with strength comparable to anything that has come before.
