  • Patent number: 8323398
    Abstract: The disclosure concerns cost effective concrete formulations based on an alkali activated binder. The construction material of the concrete type, contains sand, fine aggregates, coarse aggregates, water and a binder comprising: from 55 to 80 wt. % of fly ash containing less than wt. 8% of CaO; from 15 to 40 wt. % of blast furnace slag; a chemical activator containing: from 0.8 to 4 wt. % of alkaline silicates; and from 1.5 to 9 wt. % of alkaline carbonates; wherein the chemical activator has an silica to alkali molar ratio from 0.1 to 0.55; and a booster comprising at least one strong base. The disclosure also concerns a method to produce such a concrete construction material.

  • Publication number: 20090217844
    Abstract: 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.
