Abstract
Studies of failed engineering structures have found that soluble salts can cause extensive breakdown to sandstone and cement. The mechanism for this failure is postulated to result from crystal growth pressures as evaporate minerals crystallize in the pores. This postulated mechanism. however, is inconsistent with the thermodynamic theory as crystal precipitation and growth should occur in the most energetically favorable setting. We will test this hypothesis by examining the corrosion behavior of sandstone when it is constantly submerged in saline solutions (without crystal formation). A number of tests will be performed in order to observe the effect of saline solutions on sandstone matrix dissolution. The tests are performed on Jacobsville sandstone that was acquired from a construction site in Marquette, Michigan. A synthetic sea water, brine solution and deionized water will be used. Samples are placed in closed container containing one of the solutions. Samples are undergoing tests at room temperature, 90°C, and 200 °C. Degraded samples will be periodically examined in order to see the effects of salt corrosion and/or crystallization.
