Title: The Innovative Contributions of William H. Kellet
Introduction
William H. Kellet is a notable inventor based in Coalville, GB. He has made significant contributions to the field of cementitious compositions and their applications in underground mining. With a total of 2 patents to his name, Kellet's work has had a meaningful impact on the industry.
Latest Patents
Kellet's latest patents include innovative methods for stowing cavities with flowable materials. One of his notable inventions is a quick-setting cementitious composition that contains, by volume, 1-30% of a cement mixture including Portland Cement, calcium aluminate, and calcium sulphate, along with 0.001-5% of clay and water in excess of 65%. This composition is particularly suited for filling cavities in underground mines and constructing roadside packs. The various components of the composition can be separately pumped or conveyed to the cavity, enhancing its usability.
Another significant patent focuses on accelerating agents for hardening cement. This agent is designed for use in underground mining installations that employ concrete-like packs, including run-of-mine coal. The agent comprises one and a half parts triethanolamine, five parts sodium carbonate, and one part potassium carbonate by weight. This innovative approach prevents the too rapid setting of quick-setting cement by mixing a slurry of cement in water with a slurry of the agent and run-of-mine coal in bentonite immediately before being added to a pack.
