Cement Considered to Be Burned by Dietzsch Kiln Rmaining in a Concrete Produced in the Taisho Era ─petorological and Mineralogical Observation by Polarizing Microscope─

Puntos clave

• This study aims to analyze the mineralogical and petrographic properties of cement used in historical concrete from the Taisho era.
• Extracted concrete core from the Old Onoda Cement Factory's rotary kiln base.
• Investigated cement used, presumed to be from Dietzsch kiln based on historical context.
• Conducted observations using a polarizing microscope to assess mineral characteristics.
• Dietzsch kiln cement exhibits intermediate characteristics between those of traditional kilns and rotary kilns.
• Distinct mineralogical features were identified, differing from both traditional and rotary kiln produced cements.
