good morning
we are facing problem at site for achieving the below shell DEP requirement for the tank foundations sand compaction
The first sand layer shall be compacted with a
plate vibrator to achieve a minimum strength or density of 5 MPa or 98 % Proctor.
The thickness of the compacted layer shall not exceed 0.3 m. The sand shall be
placed and compacted at Optimum Moisture Content ± 2 %.
note the sand saving show 99% less than 5 mm passing
if any recommendation how to achieve this value please help

RE: good morning we are facing prob
A lift thickness of 0.3m is too thick to be compacted properly with a small plate compactor. Forget the 5MPa requirement and compact to 98% of the Proctor. That's easily tested.
The key to getting compaction will be controlling the moisture content. Keep it as close to optimum as possible.
