Borehole Plugging Program (Waste Disposal). Report 2. Petrographic Examination of Several Four-Year-Old Laboratory Developed Grout Mixtures
Specimens from five grout mixtures had been stored in either simulated brine groundwater at 73 F or in laboratory air for approximately 4 years. The variables included type of cement, use of a natural pozzolan, and use of salt in two mixtures. Available specimens were inspected; a specimen stored wet and one stored dry from each grout mixture were examined by X-ray diffraction for phase composition and by scanning electron microscopy to study microstructure. The results showed that: (a) Cracking of specimens were common; it was believed to be due mainly to temperature change and/or moisture change effects; (b) The mixture variables were generally not recognizable; and (c) The phase composition and microstructure of the five grout mixtures were considered normal.
