Based in Busan Gamcheon Port, South Korea, Dongwon Cold Storage specializes in low-temperature distribution, shipping frozen seafood products to major ports around the world. The company's facility is equipped with 61 rooms of various temperatures and sizes.
In 2020, the company needed to repair 40,000 square feet of flooring that was cracked and damaged due to heavy forklift traffic carrying large crates of tuna and other seafood. Because the flooring was located in a climate-controlled cold-storage warehouse, not just any concrete repair materials would do. Construction contractor Starcon used
Rapid Set® Cement All®
all-purpose repair material and
Rapid Set TRU® Self-Leveling
architectural topping to make all repairs and achieve a polished concrete appearance.
Made with belitic calcium sulfoaluminate cement (BCSA), Rapid Set products set and cure much faster than portland cement-based materials because of the cement's unique chemistry. They produce virtually no bleed water that can potentially freeze and crack concrete, so curing in lower temperatures (50 degrees Fahrenheit and lower) is typically not an issue. Instead, they retain moisture and generate heat during the hydration process, enabling the material to harden and dry in one to four hours and achieve structural strength in one hour.
The project needed to be completed in six days. To meet the tight deadline, the contractor employed both day and night crews. The 40,000-square-foot floor was divided and poured in multiple sections. Hippo mixers were used to mix all Rapid Set products.
