According to GlobalData’s company profile on Taiheiyo Cement, Artificial concrete aggregates was a key innovation area identified from patents. Taiheiyo Cement's grant share as of July 2024 was 43%. Grant share is based on the ratio of number of grants to total number of patents.
The granted patent US12054426B2 introduces a hydraulic composition specifically designed for use in additive manufacturing devices. This composition consists of sand, an inorganic binder, and polyvinyl alcohol, adhering to specific mass ratio conditions. Notably, the mass ratio of sand to the combined weight of the inorganic binder and polyvinyl alcohol must range from 4 to 12. Additionally, the ratio of polyvinyl alcohol to the inorganic binder is required to be between 0.1 and 0.4. The inorganic binder is characterized by the presence of amorphous calcium aluminates, which must constitute at least 50% but less than 100% of the total binder composition, potentially combined with a rapid-hardening cement.
Furthermore, the patent outlines an additional condition for the hydraulic composition, stipulating that the mass ratio of water to the combined weight of the inorganic binder and polyvinyl alcohol should be maintained between 0.30 and 1.30. The patent also describes a method for producing a casting mold using this hydraulic composition. This process involves mixing the specified components to prepare the hydraulic composition, followed by spreading it within the additive manufacturing device to form the casting mold. This innovative approach aims to enhance the efficiency and effectiveness of additive manufacturing processes, particularly in mold production.
