Problem
1. When a saturated cement paste is dried, the loss of water is not directly proportional to the drying shrinkage. Explain why
2. In a hydrating cement paste the relationship between porosity and impermeability is exponential. Explain why.
3. Draw a typical sketch showing how the microstructure of hydration products in the aggregate-cement paste interfacial transition zone is different from the bulk cement paste in concrete.
