Zusammenfassung:PROBLEM TO BE SOLVED: To provide a concrete material, a concrete structure and its manufacturing method which inhibit or prevent a crack caused by dry shrinkage which makes an initial defect, particularly, in a slab and a plane member constituting a structure such as a wall or the like whose crack by the dry shrinkage becomes apparent. SOLUTION: The concrete material comprises a low exothermic cement, a low additive expanding material and aggregate and has a unit quantity of the low additive expanding material is 12.5-27.5 kg/m3.
