Small Batch for Bench Testing

1. Purchase a small soap foamer and 7th Generation Dawn Soap

2. Ratio is 2 cups of 7th Generation Natural Dish Liquid in 5 gallons of water. Scale this for your size of foamer.

3. Find a suitable container to test your mix in. Measure out portland cement + water ( ratio as on bag) to fill 1/6th of container. Fill the rest of the container with foam and mix well. 

4. Wait 24 hours for the aircrete to set. 

5. Purchase an aquarium air pump with matching vinyl tubing. 

6. Drill a small hole and insert the viny tubing into the bottom of the air crete. 

7. Add water to the air crete and add CaCl2 and wollastonite to the water. Turn on the air pump and allow the pump to bubble air through the aircrete.  ( amount of CaCl2/Wollastonite depends on size of container)

8. Periodically you can use a phenolphthalein indicator to test for the acidity of the solution. When you add new CaCL2/wallastonite the mixture will turn pink. As you sequester CO2, the mixture will turn clear signifying you should add more cations sources.
