Know the inspection and soundness testing requirements of cold water systems and components LO12. Fineness Test of Cement Procedure. The soundness test repeatedly submerges an aggregate sample in a sodium sulfate or magnesium sulfate solution. This process causes salt crystals to form in the aggregate’s water permeable pores. The formation of these crystals creates internal forces that apply pressure on aggregate pores and tend to break the aggregate (Figure 1). × 4 in. Other apparatus used in the Le Chatelier Apparatus test are. The free lime and free magnesia obtained in cement causes unsound cement.
