When the weather condition was unusually hot and dry following finishing, the particular cement must have been regularly wetted to avoid fast treating. More over, in case the climate dropped close to or perhaps below the freezing level within the first couple of days of treating, the actual concrete could have been affected.

This kind of re-bar is really the main component giving strength towards the cement. If this is incorrectly put in, or undersized, well then more breaking as well as transferring is much more probable. As with the actual compressed fill, determination of this might be difficult afterwards.
