| titleOfInvention | Method of placing concrete and fresh concrete |
| abstract | PROBLEM TO BE SOLVED: To provide a concrete placing method in which generation of a primary lining concrete in a SENS method is less likely to cause defects and cold joints. According to a preferred embodiment of the present invention, a concrete placement method includes excavating a natural ground and moving a placement device having a supply port along the excavation direction to the excavation surface of the excavated natural ground. In a concrete placement method for placing concrete on an excavation surface by supplying fresh concrete from a supply port of an installation device, the fresh concrete is cement, aggregate, water, an aromatic compound having a sulfonic acid group or its A composition containing at least a salt and an alkyltrimethylammonium salt is used, and fresh concrete is supplied in a state where the stiffness ratio is 10% or less.
