Title: The Innovative Contributions of Steven W. Graville
Introduction
Steven W. Graville is an accomplished inventor based in Eugene, OR (US). He has made significant contributions to the field of materials science, particularly in the area of concrete reinforcement. His innovative approach to densifying colloidal silica has garnered attention in the industry.
Latest Patents
Graville holds a patent for a "Method for compacting silica fume." This invention presents a straightforward method for densifying colloidal silica, which is recovered from a smelting process. The method involves feeding colloidal silica, with a density ranging from about 50 kg/m³ to 300 kg/m³, through a nearly horizontal feed mechanism to a pair of vertically aligned pressure rolls. These rolls have surface depressions that correspond to the undepressed surface areas of the opposing roll. Notably, this method does not require the deaeration of colloidal silica prior to densification and can be executed as a continuous process. The densified colloidal silica produced by this method is particularly effective as a reinforcing agent for concrete.
