Title: Innovations of Kuo-Ji Yen in Rubberized Concrete
Introduction
Kuo-Ji Yen is a notable inventor based in Taipei, Taiwan. He has made significant contributions to the field of materials science, particularly in the development of rubberized concrete. With a total of 3 patents, his work focuses on improving the mechanical properties of concrete using waste materials.
Latest Patents
One of his latest patents is a method for producing improved rubberized concrete using waste rubber tires. This innovative approach involves the partial oxidation of crumb rubber derived from environmentally hazardous waste tires. The resulting surface-treated crumb rubber is used as a blending stock for creating rubberized concrete with substantially improved mechanical strength compared to conventional methods. The chemically more active rubber surface becomes hydrophilic, enhancing its interaction with the hydrophilic surface of the surrounding cement matrix. This advancement makes the mechanically improved rubberized concrete more versatile than traditional options.
Another significant patent by Kuo-Ji Yen is a method for producing rubberized concrete using waste rubber tires. This process utilizes catalytic partial oxidation with a metal oxide catalyst to treat crumb rubber recovered from waste tires. The advantages of using catalytically oxidized crumb rubber include superior mechanical strength, water-repelling capability, lower oxidation temperature, shorter oxidation time, and accelerated hydration times. Additionally, the rubber oil co-produced from the partial oxidation process is equal to or better than commercial superplasticizers. The industrial-scale partial oxidation employs a continuous flow tubular reactor, where a crumb rubber/catalyst mixture is fed into the reactor co-currently with an air/nitrogen mixture.
