QUESTION 1
(a) Using Bogue's equation below, identify these four types of Portland cement based on their chemical compound compositions. (Calculation must be included in the answer)
C3 S = 4.07(CaO) - 7.60(Si02 ) - 6.72(Al203) - 1.43(Fe203) - 2.85(S03)
C2S = 2.87(Si02) - 0.75(3CaO.Si02)
C3A
2.65(Al203) - 1.69(Fe203)
