Dongyang Launches 'Winter Season Optimized' Ready-Mix Concrete

Securing Stable Strength in Low-Temperature Environments

Dongyang, a subsidiary of Eugene Group, announced on the 10th that it has launched a cold-resistant concrete that can be stably used even in low-temperature environments where the minimum temperature drops to minus 10 degrees Celsius, and has begun full-scale field application.

The cold-resistant concrete introduced by Dongyang this time is designed to secure strength without initial freezing even at low temperatures. While maintaining workability during ready-mixed concrete placement, it solved quality degradation issues. Compared to existing products, it shortened the time to reach the target strength by 8 hours, enabling the removal of horizontal formwork within 40 hours, thereby minimizing delays in winter construction processes, Dongyang explained.

In addition, stable strength development is possible without heating curing methods such as using lignite or hot air blowers, reducing fire risks and ensuring worker safety. Furthermore, considering high floor heights and large slab areas, the curing process is simplified, further enhancing the overall efficiency of the construction process.

Dongyang’s cold-resistant concrete was recently successfully applied at the Samsung E&A construction site located in Yangsan City, Gyeongnam Province. Taking this field application as an opportunity, Dongyang plans to expand demonstration tests of cold-resistant concrete and explore applicability in various environments through cooperation with major construction companies.

A Dongyang representative said, "Winter concrete construction is difficult to manage due to temperature drops, but stable construction has become possible through cold-resistant concrete technology," adding, "We will continue to develop cold-resistant concrete technology that can be applied in various environments."
