  • 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.

  • Patent number: 7727330
    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.

  • Patent number: 5766382
    Abstract: A thermal treatment installation for treating and quenching pieces (22) of small dimensions comprises a treatment line (LT) including a treatment furnace (2) for bringing the pieces to treatment temperatures, a quenching cell (4) located downstream from the furnace, and a transport apparatus for displacing the pieces along the treatment line. The pieces to be treated are placed in baskets (20) and the baskets are grouped into charges or distinct lots forming a volume (V) having a height (H) substantially less than the other dimensions (L1, L2) of the volume. The transport apparatus comprises several driving devices (DE1, DE2, DE3, DE3' AND DE4) which are individually regulated by a regulation circuit (UC) to at least three speeds including an input speed (V1), a treatment speed (V2) and an output speed (V3) to divide the treatment line into sectors so that locally along the treatment line the baskets move at different speeds.
