Title: **Bruno Le Rolland: Innovator in Hydraulic Binder Technology**
Introduction
Bruno Le Rolland is a notable inventor based in Oinville sur Montcient, France, who has made significant contributions to the field of hydraulic binders. With a total of 6 patents to his name, Le Rolland stands out for his innovative approaches to treating polluted soils through advanced binder materials.
Latest Patents
One of Le Rolland's latest patents involves the development of a sulfoaluminate clinker based hydraulic binder. This binder is characterized by its composition, which includes mineralogical phases such as ye'elimite (C4A3$), mayenite (CA), free lime (CaO), and optionally belite (C2S). The specific ratios of these components are critical, with the ye'elimite phase making up 20% to 50% by weight, mayenite phase constituting 5% to 80% by weight, and a small proportion of free lime.
This hydraulic binder is particularly useful for treating polluted soils that have a leachable fraction exceeding 0.4%, primarily containing anions and/or heavy metal cations. Le Rolland describes a process that enables stabilization of such soils by mixing them with the binder in a proportion ranging from 1 to 40 parts of binder for every 100 parts of soil. This innovation facilitates the stabilization of polluted soils and is crucial for preventing environmental hazards.
