Yes, we have been busy working on the next generation of Beachstone and it doesn't include portland cement. Currently, we use very little cement in our mix design on purpose. The less you can use the better as it is the only ingredient we have that represents some contribution to greenhouse gas emissions. Could we make Beachstone without it? No. Then all of our recycled glass aggregate would end up in the landfill. Bad.
So, what can we do about it? Make a better cement I say! Is it easy? No. Can it be done? Maybe.
We are putting together a grant proposal for the National Science Foundation's SBIR PHase I grant. It is a big research and development grant geared towards funding innovative and disruptive technologies which have some commercial viability. So we are working on a calcium free, white, cement that has 40% less greenhouse gas emissions, which would bring Beachstone down to an unbelievably small level.
The lack of calcium could benefit other concrete products manufacturers by removing efflorescence, that unsightly white stuff that bleeds out from buildings.
Is your company or someone you know interested in this new concrete? Drop me a line and we can discuss future potential licensing arrangements.
