1. a. Consider 315 grams of original cement, determine the degree of hydration, if anhydrous cement occupies a volume of 50 c.c.

1.b. For w/c=0.63, degree of hydration=1 and 315 g of original cement, what is capillary porosity volume?

2. For the following degree of hydration: 25, 50, 75 and 100 %, determine the variation in compressive strength as a function of gel/space ratio “X”. Work with w/c ratio of 0.3, 0.4, 0.5, 0.6.

3. Plot the variation of capillary porosity at w/c ratio of 0.3, 0.5, and 0.7 at the following degree of hydration: 25%, 50%, 75% and 100%. Comment on the physical meaning of the results.
