<p>It's been a million years since you made this post, and I was wondering if you were successful with your project, and if you discovered a source for pozzolan on the Island? You could probably make lime from seashells. If true, I have a project uniquely suited to the Islands.</p>

<div>I just found out that there is a large deposit of volcanic ash in the Ka'u desert on the leeward side of Kilauea. Does anyone know if this ash is Pozzolanic? Pozzolana is what the Romans used to create cement, still standing more than 2000 years old, and it can set submerged in water. It is a low temperature cement. Class F fly ash is also Pozzolanic.</div>

<p>Maybe, but, I absolutely don't want my drinking water siting around in plastic, even the approved stuff, for long periods of time. It's not really about the water tank. The point is more of an experiment to see if the geopolymer thing can be done with local minerals. Hawaii should minimize importation of food, fuel, and building materials. The basics of life. Food is easy to accomplish. People are working hard on the energy thing. I haven't really seen people focus on building…</p>

Food is easy to accomplish. People are working hard on the energy thing. I haven't really seen people focus on building material. If a local cement could be found that would be a big step. I don't know, maybe someone has already done it. But, geopolymers are starting to be big. Check out:</p>

<p>They are calling it a carbon negative cement. I think Grancrete is in the magnesium phosphate family of cements.</p>
