Given a selection of 28 day cube test results for concrete placed of design mix C 35 and not all of which are greater then 35 MPa, how does one decide if the concrete in place is satisfactory. Are there a minimum number of cubes that need to be tested to decide that?
Answer Posted / raju goyal
As per my view : At the time of casting of any structure we would have to taken six samples from the each load or batch in which 3 samples keep 7days and 3 samples for 28 days testing. The 7days samples should have minimum 75 % strength and 95 % strength in 28 days should be gained of it's characteristics strength .

Design a cantilever type retaining wall to retain sand for 4m above the ground. The sand fall slopes at the rate of 1 vertical to 2 horizontal. The weight of sand is 18000 N/m3, the angle of repose being 30. The safe bearing capacity of the soil is 200 kn/m2 at 1/25m below the ground level. Use m 15 concrete mix.
