The production technology of three indications is leading the industry.
In 1980, we
succeeded in replacing bunker C oil with bituminous coal for the first time in Korea to cope with the energy surge , contributing to energy saving. In 1995, we obtained a Certificate of Cement Quality Inspection from the Ministry of Construction of Japan
and exported more than 200,000 tons per year to the Japanese market . In 1999, it
was the first Asian country to receive the
LIP (Laboratory Inspection Program) certification from CCRL (Cement & Concrete Reference Laboratory) belonging to the National Institute of Standards and Technology (NIST ) Materials
has been recognized for its rigorous testing environment and test technology. Since then, we have been
participating in the CCRL's Proficiency Sample Program (PSP) Physical Test twice a year and have been highly evaluated for its technology and reliability in ASTM testing. In addition
to advanced automatic monitoring and control facilities, the three-indicator system uses a statistical quality control system to analyze the
quality of the products. There is.
