- If it is observed that seven days’ strength is less, then the following precautions should be taken.
- Increase the de-shuttering period of the particular slab and wait for the results of twenty-eight days’ strength.
- Locate the position on the slab and test the strength with normal hammering. It should give a ringing sound for better strength concrete.
- If the slab gives a different sound, then break the particular portion and re-concrete after consulting the structural consultant.
- If the structural consultant is satisfied with the strength of concrete at site, even after the poor result of a particular cube, then the report should be sent to the Chief Engineer accordingly, for acceptance of the concrete quality.
2. FOR R.C.C. WORK, OUT OF PLUMB AND LINE
Rectify any defects through the demolition of the faulty work and re-concrete it. Necessary precautions should be taken as mentioned below

- All cracks should be grouted with cement slurry.
- Sometimes It becomes necessary to make openings in a cast slab, e.g,, for creating access from the basement to the top floor, by breaking the R.C.C. slab or extending balcony portion porch, by increasing cantilever bracket length, etc. For such rectifications, the following precautions should be taken.
- Any change in R.C.C. work should be done after consulting the structural designer.
- Support and brace all adjacent work properly.
