| Description: | Miscellaneous Paper Abstract: Two concrete mixtures were developed in 1983 for possible use in repository sealing application. The salt concrete was basically an adaptation of BCT 1-F salt grout made by adding aggregate. The nonsalt mixture was a similar adaptation of nonsalt BCT 1-FF grout. The basic requirement was continued workability after 2 hr of intermittent mixing. Tests of hardened specimens included strength, modulus of elasticity(E), permeability, coefficient of linear thermal expansion, thermal conductivity, expansion, creep, and examinations by X-ray diffraction for phase composition and by scanning electron microscopy for microstructure. Some of the physical tests were done on specimens that had been kept at 23 ± 1.7° C and on other specimens kept at 61 ± 2° C. Tests for expansion and examinations for phase composition and microstructure are being continued at 6-month or yearly intervals. It was concluded that each concrete mixture was a viable candidate for use in repository sealing applications. |
