Strength of Cemented Hydraulic Sandfill Modified by Flocculants.
NTIS: PB 253 006 :14 pages
The strength characteristics of hydraulic sandfill modified by varying quantities of type III portland cement and two flocculants were investigated by the Bureau of Mines. Three different sand- cement ratios were examined using different percentages of flocculant. Two other experimental variables were curing time and weight-percent solids for hydraulic mixture. Results of unconfined compression tests with strain are discussed. Maximum strength was achieved with 0.5 Weight-percent of ferric sulfate per ton of solids when the slurry mixture was 75 weight-percent solids. The bearing capacity of hydraulic sandfill is reduced by increasing the water content and decreasing the amount of cement mixed with sandfill.
