Lotte Construction Develops Korea's First Next-Generation Admixture... Concrete Strength Up 10%

Development of Next-Generation Concrete Admixture with Enhanced Performance

On May 15, Lotte Construction announced that it has developed a next-generation concrete admixture with improved performance, in collaboration with Lotte Chemical and Silkroad C&T, a manufacturer and distributor of concrete admixtures. After a year of joint research, the partners succeeded for the first time in Korea in replacing the core raw material of the admixture with a new material.

This technology reduces the viscosity of concrete before it hardens, making it easier to handle. It is especially effective for the construction of narrow or complex structures. Compared to existing products, it increases compressive strength by more than 10% and reduces water usage during concrete production by 10%. While admixtures may be unfamiliar to general consumers, they are essential materials for ready-mixed concrete companies and construction firms.

This research was conducted in line with the Ministry of Land, Infrastructure and Transport's ongoing policy to "strengthen the safety of construction structures." Lotte Construction aims to proactively respond to government policy and to strengthen its position as a construction company with technological competitiveness.

Lotte Construction plans to expand the application of this admixture to all of its sites starting in the second half of this year. The company intends to emphasize the effectiveness of the technology by immediately deploying it in actual construction sites, rather than merely announcing research results.

Seok Wongyun, head of Lotte Construction's Technology Research Institute, said, "We expect improved work efficiency and constructability at construction sites," adding, "We will continue to enhance our quality competitiveness through ongoing technological development to become a construction company that delivers the highest quality to our customers."
