Your cement company manufactures a cement with the following composition: 55% C3S, 18% C2S, 10% C3A, 8% C4AF, and 6% CŜH2 with a Blaine fineness of 365 m2 /kg. a. A customer has complained that the 1-day strengths are low. List 2 things you can change in your production to address this and what the consequences of those two things are on the composition and properties listed above. b. Which of the two changes in (a) are you more likely to implement, and why? c. All of a sudden there is a high demand for gypsum and the price has skyrocketed. What can you do to your cement to reduce the amount of gypsum needed? What would a potential consequence of this change be?
