POSCO E&C Initiates Development of High-Performance Concrete

[Asia Economy Reporter Yoo In-ho] POSCO Engineering & Construction recently announced on the 3rd that it has signed a technology agreement with S-Oil and two small and medium-sized enterprises to begin developing high-performance concrete using steel and petroleum byproducts.

POSCO Engineering & Construction explained that by fusing sulfur, a petroleum byproduct, with slag generated during the steel production process to make cement, the curing speed can be increased by 10%, thereby shortening construction time. They added that this method is expected to enhance the durability of concrete and reduce material costs by 10%.

Under the agreement, POSCO Engineering & Construction will receive sulfur and other petroleum byproducts from S-Oil for 10 years, develop new cement with Beomjun ENC, which possesses sulfur cement concrete technology, and Taemyeong Industrial will participate in the development of precast concrete products.

Precast concrete refers to concrete structures that are pre-manufactured in factories and assembled and installed on-site, and it is a construction material whose usage has been increasing recently.

A POSCO Engineering & Construction official stated, “If this project succeeds, steel and petroleum byproducts that would otherwise be discarded can be recycled into competitive construction materials,” adding, “It will also be recognized as an environmentally friendly model.”
