Title: The Innovative Contributions of Karl V Hauser
Introduction
Karl V Hauser is a notable inventor based in Ann Arbor, MI, with a significant impact in the field of construction materials and waste management. He holds four patents that showcase his innovative approach to improving mortar and concrete applications, as well as reclaiming foundry sand wastes. His work reflects a commitment to enhancing material properties while addressing environmental concerns.
Latest Patents
One of Hauser's latest patents is for an "Air entraining mortar and process of manufacture." This invention involves a process and composition for treating mortar or concrete that includes fly ash containing carbon, aimed at increasing air entrainment. A small quantity of a soluble alkaline earth oxide is added during mixing to inhibit the air-adsorptive properties of the carbon in the fly ash.
Another significant patent is the "Process for reclaiming foundry sand wastes." This process treats waste foundry core and molding sand, upgrading these materials to new sand quality suitable for core making. The method involves incrementally heating the sand to temperatures between 1800°F and 2500°F, followed by cooling. This innovative approach reduces the acid demand value (ADV) and eliminates the need for mechanical attrition to remove clay additives, thus minimizing environmental pollution by burning off resins during treatment.
