Discussions about the production and use of rice husk ash cement, a pozzolana that can be combined with lime or ordinary portland cement to form a cementitious binder.
Hi Geoffrey,
thanks for all your previous help and information,
wandering if you have any embodied energy calculations for RHA MJ/kg?
Much appreciated as always!

Dear Geoffrey,
I am currently experimenting with hydrated lime and raw rice husks to build insulating panels. As a binder I would like to use a mix of lime, pozzolan and a small amount of cement to increase the initial setting and at the same time maintaining the advantage of lime (carbonation effect).
I have a few questions and I hope you can give me some advice on Lime-RHA based binder:
1) According to your experience what would be the most suitable binder mix, i.e. Lime/RHA/OPC and binder/water ratio?
2) can you please provide me your RHA specs as well.
