Problem
1. When producing a certain type of portland cement it is important that the oxide composition remains uniform. Why?
2. In regard to sulfate resistance and rate of strength development, evaluate the properties of the portland cement which has the following chemical analysis: SiO2 = 20.9 percent; Al2O3 = 5.4 percent; Fe2O3 = 3.6 percent; CaO = 65.1 percent; MgO = 1.8 percent; and SO2 = 2.1 percent.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
