Hanil Cement announced on the 14th that its "ultra-maintained concrete" technology, jointly developed by Hanil Cement and Hanil Industries, has obtained technical performance certification in the field of construction and construction materials from the Korea Architectural Engineering Association.

Applying the technology certified this time reduces quality changes caused by fine powder (differentiation), preventing material separation in the ready-mixed concrete dough and securing stable initial strength of the building. The existing method of manufacturing ready-mixed concrete had the disadvantage of deteriorating concrete quality when a large amount of fine powder was included in aggregates such as sand and gravel.

Ultra-maintained concrete is a product developed by combining the mixing technology of Hanil Industries and the cement material technology of Hanil Cement. Liquidity can be maintained for up to three hours after production, even in hot weather with an average temperature of 35 degrees. If not poured within 90 minutes, it can secure more than twice the working time compared to regular concrete, which is optimized for installing site in urban areas with frequent traffic congestion. In addition, it has the advantage of being able to adjust the production mix for each season and construct it at a constant quality throughout the four seasons regardless of climate conditions.

"With this certification, the excellence of technology that can solve quality concerns at construction sites has been objectively recognized," said an official at the Hanil Cement Technology Research Institute. "We plan to actively respond to the demand for construction sites through various solutions in the future."
