Title: Innovations of Liang-Hsign Chou in Rubberized Concrete
Introduction
Liang-Hsign Chou is a notable inventor based in Chia-Yi, Taiwan. He has made significant contributions to the field of construction materials, particularly in the development of rubberized concrete. With a total of 3 patents to his name, Chou's work focuses on enhancing the mechanical properties of concrete using waste materials.
Latest Patents
Chou's latest patents include 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 utilized as a blending stock for creating rubberized concrete that exhibits substantially improved mechanical strength compared to conventional rubberized concrete. The chemically more active rubber surface becomes hydrophilic, allowing for a stronger interaction with the hydrophilic surface of the surrounding cement matrix. This advancement makes the mechanically improved rubberized concrete more versatile than its conventional counterpart.
Another significant patent by Chou is a method for producing rubberized concrete using waste rubber tires. This process employs catalytic partial oxidation with a metal oxide catalyst to treat crumb rubber recovered from waste rubber tires. The advantages of using catalytically oxidized crumb rubber include superior mechanical strength, enhanced water-repelling capability, lower oxidation temperature, shorter oxidation time, and accelerated hydration times. Additionally, the rubber oil co-produced from the crumb rubber partial oxidation process is equal to or better than commercial superplasticizers. The industrial-scale partial oxidation utilizes a continuous flow tubular reactor, where a mixture of crumb rubber and catalyst is fed into the reactor alongside an air/nitrogen mixture.
