A method for forming concrete comprising:
- pouring a dry cement powder into a mold;
- and
- without mixing the dry cement powder with liquid water, conveying water vapor through said dry cement powder;
- wherein said water vapor hydrates said cement powder, creating a crystalline structure, and
- wherein:
- the mold has one or more surfaces that are permeable with respect to gaseous water but not with respect to cement particles;
