[Asia Economy Reporter Kim Hyemin] Hyundai Engineering & Construction announced on the 18th that it has developed the world's first high-strength concrete using porous glass powder and will apply it to sites such as the Godeok Bridge construction.

Porous glass powder is a new spherical material composed of fine powder particles. In the case of high-strength concrete, chemical admixtures are used to reduce viscosity, but Hyundai Engineering & Construction utilized porous glass powder instead. This is because chemical admixtures are often affected by external temperatures, making it difficult to secure the workability of high-strength concrete.

The high-strength concrete developed by Hyundai Engineering & Construction can significantly reduce viscosity even with a small amount of porous glass powder, and since it is not affected by external temperatures, it can also secure the workability of high-strength concrete. The low viscosity is advantageous for pouring and finishing work.

Hyundai Engineering & Construction has completed the demonstration of high-strength concrete using porous glass powder and has applied it to the Ijin Bay City and Godeok Bridge sites respectively.

A Hyundai Engineering & Construction official stated, "As buildings are becoming larger and the construction of super high-rise buildings is increasing, the importance of high-strength concrete that can withstand higher loads than ordinary concrete is growing," adding, "We plan to continuously expand the scope of application, and it will be helpful for large-scale site projects."
