SC Concrete is common in USA.  But in india it is started now.  We face problem while pumping at 160mtr vertical as well in down ward 16mtr.  Concrete choking problem.  We are using BP 2800 pump for pumping.  Can you suggest, how to lay the pipeline or reason for choking?

Never heard of it but I'll take a guess;

the mud does not want to pump after you stop, right?

my guess, the mud settles in the lower 90 when you stop pumping and separates?

Just a guess based on the name SCC.

As the mix related problem is area specific, this is based on my past 10 years exposure. So can you specify which part of india and also the grade?
