Please can anyone advise on typical grout pumping design with 1:5 mix of Portland cement:ground granulated blast furnace slag mixed with water to produce a 0.5:1 water / solids ratio grout.

Is the viscosity required or can the calculation be done based on the dry solids content, solids size and concentration?

Sure it would be useful to build a full size rig but this is a 40m long pipe (40mm diameter) and it is all horizontal and generally vertical drops. No uphill sections at all.

Regards
John

That could be a problem. Details here are sketchy but it is a well known fact that pumping concrete downhill is more problematic than pumping uphill. To what extent this comment is applicable I cant predict unless I know the size of the slag , the slurry SG etc etc etc
 
Hi Miningman,

The slurry SG is 1.773.
I am trying to find out the average particle size also.....
