Title: Takeji Okada: Innovator in Concrete Technology
Introduction
Takeji Okada is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of concrete technology, holding two patents that showcase his innovative approach to construction materials. His work focuses on enhancing the properties of concrete to improve its performance and durability.
Latest Patents
One of Okada's latest patents is for a resin-coated aggregate. This invention features a substantially water-resistant resin-coated aggregate designed for use in concrete. It includes a porous aggregate body, such as an artificial lightweight aggregate, with an elastic layer made of a phenol resin elastomer deposited on the aggregate body. Additionally, a rigid phenol resin is coated on the elastic-covered aggregate body. This resin-coated aggregate offers high water absorption prevention and an external stress-damping function.
Another notable patent is for a flowing concrete and the process of producing it. This invention involves kneading cement, water, aggregates, a superplasticizer, and a segregation-controlling agent into a base concrete with a water-cement ratio of about 35% or less. The segregation-controlling agent is included in an amount of about 0.02 to about 0.1 wt. %, based on the water, and contains a methylcellulose compound. The superplasticizer is present in an amount of about 0.25 to about 0.6 wt. % based on the cement. The base concrete is then mixed with a flowing agent, which includes a sulfonic acid/formaldehyde high condensate and polyvinyl alcohol, to create the final flowing concrete.
