Crack survey

Dear All
Upon deshuttering formwork on road barrier concrete casting the horizontal or longitudinal cracks are developing on-site as seen in the attached photo. Its new jersey crack as commonly know.
Anyone possibly ascertain the reasons and preventive measures?
Thanks in advance..

Do a petrographic examination through the crack and you'll likely see that the coarse aggregate is not fractured in the crack...the cement paste separated from the coarse aggregate as the top dried out.

These cracks are occurring on daily basis

A followup on this would be appreciated. We would like to know if your problem is solved. Many miles of New Jersey barrier have been constructed all over the world without this type of cracking, so it must be something in your process that is deficient. Settlement of the plastic concrete below top reinforcement, concrete that is too soupy, lack of consolidation, etc. have been suggested. Probably all of the above, but rather than guess, we would like to know your conclusions.
