Title: Toshihide Shimono: Innovator in Hydraulic Cement Compositions
Introduction
Toshihide Shimono is a notable inventor based in Aichi, Japan. He has made significant contributions to the field of hydraulic cement compositions, holding a total of 3 patents. His work focuses on enhancing the properties of cement to improve construction materials.
Latest Patents
One of his latest patents is for ultra high-strength hydraulic cement compositions. This innovation features an extremely low water-to-cement ratio of 10-30%, which allows for high fluidity and improved capability of preventing slump loss. The resulting high-quality ultra high-strength hardened concrete and mortar exhibit superior workability. The composition includes a binder made of cement or a mixture of cement and a microscopic powder admixture, aggregates, water, and a cement dispersion agent composed of water-soluble vinyl copolymers. The unit content of the binder ranges from 400-1300 kg/m³, with a water-to-binder ratio of 10-30% and a cement dispersion agent content of 0.1-2.0 weight parts for every 100 weight parts of the binder.
Another significant patent involves a method of providing fluidizing properties to hydraulic cement compositions. This is achieved by adding a cement dispersion agent to the composition at a rate of 0.01-2 weight % relative to its solid cement component. The dispersion agent contains a water-soluble vinyl copolymer, which is produced through the copolymerization of specified monomers. This innovative approach enhances the fluidity of the cement composition, making it more effective for various applications.
