Unformatted text preview: 6. How would you define the coefficient of permeability? Give typical values of the coefficient for (a) hardened cement pastes; (b) commonly used aggregates; (c) high-strength concretes; and (d) mass concrete for dams. 7. How does aggregate size influence the coefficient of permeability of concrete? List other factors that determine the permeability of concrete in a structure. 8. What chemical reactions are generally involved in sulfate attack on concrete? What are the physical manifestations of these reactions? 9. What is the alkali-aggregate reaction? List some of the rock types that are vulnerable to attack by alkaline solutions....
