Examination of Grout and Rock from Duval Mine,New Mexico.

摘要

Petrographic examination was made of a 17-year-old grout specimen that had been surrounded by rock salt. It was found that the contact between the grout and the rock salt was tight and that the composition and microstructure of the grout seemed normal for such material. The grout contained calcium silicate hydrate, calcium hydroxide, tetracalcium aluminate dichloride-10-hydrate, and some halite and sylvite. (Author)
