Jaime Valenzuela Grado has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Compositions of cellular materials that contain anhydrite and methods for its preparation
    Patent number: 7837786
    Abstract: The present invention describes improved cellular compositions that contain anhydrite that reaches high compression resistance values, of the order of 110 to 138 Kg/cm2, as well as methods of obtaining of these. The obtained cellular materials with the compositions of the invention can be used like constructive structural materials, and without they present the problems commonly associate to the anhydrous calcium sulphate presence in similar materials.
    Type: Grant

  • Microsilica materials with improved pozzolanic activity
    Patent number: 7537653
    Abstract: A new pozzolanic material basically conformed of microsilica with a minimum of silica of 85% in its composition is described, where the silica of the material is conformed mainly of cristobalite and tridimite. Unlike microsilica conformed basically of quartz, the microsilica of the invention exhibits greater pozzolanic indexes and provides improved characteristics of durability to concrete cements and in smaller proportions. Also simple and low consumption energy methods for obtaining the pozzolanic material of the invention are described.
