31. The Microstructure of Portland Cement Concrete
The microstructure of concrete can be divided into regions:
Cement Paste
Transition Zone between Aggregate and Cement paste
Structure of “un-damaged” Concrete
Macrostructure
Aggregates (CA, FA)
Hydrated cement paste (hcp)
Entrapped air voids
Microstructure
Hydrated cement paste
(Hydration products:C-S-H, ettriginite; monosulfate; porosity: gel, capillary pores entrained/ entrapped air voids)
Transition zone (TZ)

32. Pore Structure Pore size distribution (PSD) Pore Types Porosity
Connected
Isolated
Gel
Porosity
Capillary
Volume of Pores greater than 30 nm
Volume of interlayer pores in hydration products
Total
Volume of connected, gel, and isolated pores
