Observations and recommendations 1
One layer of Pour is 267.44 M 3 considering that the layer of 350 mm is maintained through out the pour.
2
The completion time for placement of one layer of concrete has exceeded even up to 10 Hours which clearly implies that poured concrete is set before the consecutive layer is laid thereupon and cold joints formation has taken place.
3
The SD and CoV values of CCS shall be obtained at the age of 28 days and the results shall convey only CCS of the concrete poured and not the cold joint formation in the raft.
4
The cold joint formation in the raft can be detected by appropriate NDT.
5
Epoxy grout is suggested.
6
Approriate NDT is suggested.
7
A separate meeting with reputed Design and Engineering consultant involved in R and D works is suggested if not agreed upon the observation made by FQA , APL, Mundra.
