Hello everyone

I produced small pots (pouring them into a mould) I made SCC concrete without the use of fibers. Everything is ok with them after production, they have no defects. After a few weeks of production I decided to pour water into it and after a few days they started to crack like in the picture. When they stand without water, nothing happens to them. Please help....

could you give a bit more information on the mix you are using?  I have not seen it quite this dramatic, but I have seen ASR do this.  Proper curing cured the problem when it came up in the past incidents I saw it, but without knowing what you have going on it is hard to give off the cuff answers that will help.
