Concrete and Concrete Admixtures Southeast University, located in Nanjing, China, is one of Sika’s main partners in exploring technology leadership in the field of concrete and concrete admixtures. During the scientific & technical cooperation with Southeast University, two projects, “Investigation into Influential Regularities and Mechanisms of Sika Water Reducing Agent on Concrete Volume Change” and “Investigation into Influential Regularities and Mechanisms of Sika Water Reducing Agent on Concrete Durability” were carried out. Some research results achieved in this cooperation have been applied successfully in several construction projects.
