2014 1 Development and Application of Concrete for Improved Workability and Quality Masanori Tsuzuki Yasumichi Koshiro Masaki Sakai Abstract Flowing concrete having fluidity and material separation resistance was applied to the construction of a new laboratory at our technical research institute for improved workability, and low drying shrinkage concrete using an expansive additive and reducing shrinkage agent was applied for improved quality. Compared with concrete having a slump of 21 cm, the highly fluid concrete reduced the unit cement content, and the slump loss from the mixing time was small.
