Thin shell concrete structures and ferrocement have been an interest of mine for years. I used flyash in all my recipes.
Do you use any Portland cement? What ratios of flyash, Portland and aggregate.? What grit aggregate?
What ratio would you suggest, specifically for a floating raft foundation?
What formulation of flyash do you suggest? I have used type F, even though it is a special order item.
Thanks in advance.
