Hello,
I'm looking at using slag cement and portland blend stabilized with bentonite for the purpose of backfilling an abondoned utility.
What is the best ratio between slag/portland?
My mix water will be at about 6% bentonite by wt of water, and I'm thinking a 2:1 water/slag+portland should give the 200 psi at 56 days? Does anyone have experience with a mix like this? clay

Thanks for the reply, yes sand will reduce shrinkage but will also reduce my ability to pump any great distance. I want to pump 2,000 ft +/-. I think I can live with the shrinkage with the addition of post grout pipes fixed to the top of the box. I currently have mixes being tested to confirm 200 psi. Will keep you posted on the results. clay
