Method for producing concrete formed body
A problem is to provide a production method by which a high-strength concrete formed body can be obtained. The problem can be solved by a method for producing a concrete formed body including a defoaming step [1] of holding a concrete composition having a water-cement ratio adjusted to from 14 to 20%, in a reduced pressure atmosphere to obtain a defoamed concrete; a defoaming step [2] of holding a carbon fiber immersed in a cement solution having a water-cement ratio adjusted to 14% or more, in a reduced pressure atmosphere to obtain a defoamed fiber; and a forming step of placing the defoamed concrete and the defoamed fiber within a shuttering, followed by curing to obtain a high-strength concrete formed body.
