The Green Technology Certification is a nationally recognized certification system granted to outstanding technologies that minimize greenhouse gas and pollutant emissions and efficiently utilize energy and resources, in accordance with the Framework Act on Carbon Neutrality and Green Growth.

Bluecon Speed, which received this certification, is a high-performance special concrete that achieves a compressive strength of at least 5 MPa (megapascals, equivalent to approximately 10 kg of load per 1㎠) within 24 hours after pouring at construction sites where the average daily temperature is at least 5°C.

Recently, the technology proved its excellence by achieving a compressive strength of at least 5 MPa within 24 hours even at an average daily temperature of 0°C. This has allowed the construction period per floor for apartment structural works during the off-season to be shortened by at least one to two days compared to previous methods, thereby enhancing productivity and construction efficiency on site. Market demand is also rapidly expanding. Last year, Bluecon Speed sales nearly doubled compared to 2024.

A representative of Sampyo Industrial stated, "Obtaining this Green Technology Certification is an official recognition of our product's exceptional technological capabilities and eco-friendly value. Moving forward, we will continue to prioritize quality and safety at construction sites, and concentrate our efforts on developing low-carbon, eco-friendly special concrete technologies that contribute to achieving carbon neutrality."
