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.
