Sampyo Industries and Hyundai Engineering & Construction Develop 'Seasonal Special Concrete'

Applied at Sites Including 'The Parkside Seoul' in Yongsan

Sampyo Industries announced on the 13th that it has jointly developed a ‘Seasonal Special Concrete’ with Hyundai Engineering & Construction.

This technology is expected to lead to a quality innovation by securing stable strength for concrete construction during the transitional seasons when temperatures drop below freezing. Sampyo Group

This newly developed concrete applies Sampyo Cement’s early-strength slag cement to seasonal concrete. Its key feature is the ability to reliably achieve a compressive strength of at least 5 MPa (megapascals) within 48 hours, even when the outside temperature is close to freezing (0°C).

Sampyo Industries expects that, with this development, it will be able to secure stable initial strength in seasonal conditions with large temperature fluctuations, thereby ensuring the initial construction quality of concrete and drastically reducing both management costs and required manpower.

Sampyo Group and Hyundai Engineering & Construction applied the seasonal concrete for the first time in Korea to two major premium residential complexes: ‘The Parkside Seoul’ in Yongsan and ‘Banpo DH Clast’. In tests conducted in March, the concrete consistently met target strength and performance, even amid rapid changes in outdoor temperature.

A site official stated, “After applying the seasonal concrete, we confirmed that stable strength could be achieved even during unpredictable seasonal weather. This enables more systematic schedule management and improved durability of the structures, which is expected to significantly enhance construction quality.”

Sampyo Group believes that this seasonal concrete will become a technology capable of adapting to changes in the construction environment arising from climate change. By minimizing quality defects that can occur in various environments and maintaining a consistent hardening rate, the company explained that it will also improve the safety and work efficiency of subsequent processes, such as the removal of formwork.

A representative from Sampyo Group said, “Having led the way in special concrete technology, Sampyo Group has achieved a technological milestone in responding to climate change through collaboration with Hyundai Engineering & Construction. Going forward, we will continue our efforts to develop high-performance concrete technologies that solve challenges at construction sites and enhance the quality and value of buildings.”
