en.Wedoany.com Reported - Hyundai E&C recently obtained the Green Technology Certification from the Ministry of Land, Infrastructure and Transport of South Korea for its early strength concrete technology, which significantly reduces energy consumption during the concrete curing process. This technology was jointly developed by Hyundai E&C, Hyundai Engineering's construction technology research organization HMG Institute of Construction Technology, and Sampyo Industry.

This technology, named "Process Technology for Applying Early Strength Concrete in On-Site Concrete Works Under Conditions Where the Daily Average Temperature is 5°C or Higher" (referred to as early strength concrete technology), utilizes a C-S-H (calcium-silicate-hydrate) activator that is crushed and formulated at the nanoparticle level. When the ambient temperature reaches 5°C, it enables the concrete to achieve a strength of over 5 MPa within 18 to 24 hours without the need for additional heating.

Traditional concrete requires creating a construction environment above 10°C and using fossil fuel heating for at least two days to achieve a strength of 5 MPa in winter. In contrast, early strength concrete only requires an ambient temperature above 5°C to achieve 5 MPa strength within 24 hours, rapidly obtaining the required performance and quality with minimal heat supply.

In the Green Technology Certification evaluation, it was confirmed that this technology reduces carbon emissions by more than 55% and process emissions of hazardous substances (8 types) by over 54% compared to ordinary concrete (Type 1 ordinary Portland cement concrete). Due to its outstanding performance in preventing collapse during winter construction projects, this technology has been designated as a new disaster safety technology by the Ministry of the Interior and Safety of South Korea, marking the first time for a concrete technology to receive such recognition.
