Abstract:
Atomic Energy of Canada Limited is researching cement-based grouts for possible use in sealing a nuclear fuel waste disposal vault. The reference grout adopted for further study consists of reground sulfate-resistant cement, water, silica fume, and superplasticizer. The silica fume and superplasticizer are added to achieve a workable, nonbleeding, dense, and durable grout that exhibits very low hydraulic conductivity. Paper describes the results of laboratory studies to determine the effects of silica fume and superplasticizer contents on viscosity, bleed, setting time, strength, and shrinkage of the grout. The data show that grout mixes incorporating a range of superplasticizer and silica fume contents exhibit no undesirable properties that would raise concerns over the reference grout mix design content.
