Samples of a silicate cement were soaked in different environments for varying lengths of time. The resulting solutions were analyzed for Na, Zn, Ca, Al, and Si by atomic absorption spectrophotometry. All of the elements showed a decreasing rate of solution with increasing time. Citric acid was particularly destructive and it was found that this medium leaches Al at a far greater rate than the other mediums.
