Problem
1. How many types of water are associated with a saturated cement paste? Discuss the significance of each. Why is it desirable to distinguish between the free water in large capillaries and the water held in small capillaries?
2. What would be the volume of capillary voids in an 0.2-water-cement ratio paste that is only 50 percent hydrated? Also calculate the water-cement ratio needed to obtain zero porosity in a fully hydrated cement paste.
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.
