Title: Innovations by Jean-Pierre Letourneux
Introduction
Jean-Pierre Letourneux is a notable inventor based in Villefontaine, France. He has made significant contributions to the field of materials science, particularly in the development of hydraulic binders and waste treatment methods. With a total of 2 patents, Letourneux's work has implications for both construction and environmental management.
Latest Patents
Letourneux's latest patents include a clinker hydraulic binder and a treatment method for urban waste incineration residues. The first patent describes a clinker-type hydraulic binder obtained by burning, which comprises a magnesia spinel mineralogical phase and at least a calcium aluminate mineralogical phase. This binder has a lime content of less than 15% of the binder by dry weight. The magnesia spinel represents between 68% and 81% by dry weight of the binder, and the calcium aluminates consist essentially of CA and CA, with C═CaO and A═Al O. This invention is particularly useful for making refractory concrete, especially for steel ladles and their wear lining.
The second patent focuses on a treatment method for urban waste incineration residues. In this method, the residues are homogenized and subjected to chemical analysis. They are then mixed with water and a reagent containing active alumina in proportions determined by the chemical analysis, generating complex aluminates while ensuring that active alumina is in excess.
