1. first, calculate how much mixing water you need in gallons 6.3 galsk 84.33 sk 531.28 gallons 2. as there are 42 gal in a barrel, convert to barrels 531.28 gal 42 galbbl 12.65 barrels accordingly, it will take this quantity of water to mix such cement.1
2. calculate a theoretical amount of cement needed prior to the beginning of the grouting operation. 3. the cement and water shall be mixed at a ratio of 5.2 gallons of water to one 94 lb. bag of portland cement. 4. should the cement return to the surface with less than the acceptable amount, then the tremie pipe should be moved to clear the annulus.2

How to calculate water cement ratio. the water to cement ratio is calculated by dividing the water in one cubic yard of the mix in pounds by the cement in the mix in pounds. so if one cubic yard of the mix has 235 pounds of water and 470 pounds of cement the mix is a .50 water to cement ratio. if the mix lists the water in gallons.
In general, with bentonite cement slurry densities are from 11.5 to 15.0 ppg. bentonite can be mixed in two ways. it can be directly mixed with cement dryblended and later the blend is mixed with watermix watermix fluid or it can be mixed in the mix water prehydrated and later cement is added in the mixed fluid.
Lon batch of cementlime grout, 150 pounds of hydrated lime can be replaced by using about 25 pounds of bentonite powder. mix design rules in order to keep field procedures simple the emphasis should be on controlling the watercement ratio. this is accomplished by mixing the cement with the waterfirst.thisiscontrarytoprocedures.

Neat cement is more fluid than a high solids bentonite and typically allows more time before it sets, thus making is easier to place the grout. in most cases, we chose a readymix truck to bring the grout to the site, so it also eliminated the laborintensive task of mixing 94 pounds bags of portland cement.
