Latest Patents

Hideki Endo holds 1 patent for his invention titled "Compositions for low heat cements." This invention is specifically designed for massive concrete works and exhibits a compressive strength/heat of hydration ratio of at least 7.0 at the age of 13 weeks. One of his inventions involves a powder prepared by mixing CaO, SiO₂, and Al₂O₃ materials, melting the mixture, quenching the melt, and grinding the quenched matter. The resulting powder is composed mainly of amorphous substances and has a CaO/SiO₂ molar ratio of 0.8-1.5, with an Al₂O₃ content of no more than 10 wt. %. The second invention provides a mixed powder comprising no less than 70 wt. % of the first powder and no more than 30 wt. % of an addition, such as Portland cement. This mixed powder maintains the predominance of amorphous substances and the same CaO/SiO₂ molar ratio, with an Al₂O₃ content of less than 12 wt. %.
