Description

High-fluidity concrete was applied for concrete filled steel tubular columns in the construction of the North Tower of the Nakono-sakaue 2-chome urban redevelopment project. The concrete works were conducted under the newly established guideline for high-fluidity concrete by Housing & Urban Development Corporation. In the construction, high-strength light-weight concrete with the design strength of 30 MPa was pumped up to the 30 th floor level. Pressure of concrete pump and properties of concrete before and after pumping were measured when concrete was pumped to 10th, 21st and 30th floor.
