Hanil Cement Obtains Technology Certification for "Cold-resistant Concrete"
Strength Secured Even at Sub-zero Temperatures
Improved Winter Constructability
Hanil Cement and Hanil Industry announced on the 26th that they have jointly developed cold-resistant concrete technology capable of achieving the required strength at sub-zero temperatures without additional heating equipment, and have received technology performance certification from the Korea Institute of Building Construction.
Concrete hardens through a chemical reaction between water and cement, but when the temperature drops, the reaction rate slows dramatically. In particular, at sub-zero temperatures, internal moisture can freeze, resulting in lower initial strength. To prevent concrete from freezing at construction sites, rapid heating methods such as installing tents or operating hot air blowers have been commonly used. However, these methods incur additional costs for heating and have been criticized for increasing the risk of fire and suffocation accidents.
The newly developed cold-resistant concrete is a product that combines Hanil Cement's rapid-hardening cement with a winter additive developed by Hanil Industry. By accelerating the initial reaction rate, it ensures that concrete can achieve the required strength to meet safety standards, even when cured simply by covering with plastic or insulation sheets, without the need for separate heating equipment. The product maintains stable performance at temperatures as low as minus 10°C. Hanil Cement explained that the technology has been validated for its performance at a new office building construction site.
