The present invention concerns the development of a simple, multipurpose,
low cost, environmental friendly and safe binder formulation and related
process, based on high volumes of alkaline activated class F fly ash
residue (>760%) without ordinary Portland cement and related products,
offering a wide scope of applications. More specifically, the universal
binder is based on a very limited number of components (fly ash type F,
Blast Furnace Slag and a mixture of alkali silicates and carbonates). The
binder allows developing considerable strength at the early stage (at
room temperature) and very high resistances at 28 days. The binder
applies to pastes, mortars concretes and pre-cast with the same
flexibility of an Ordinary Portland Cement.
