- •
The shrinkage behavior of the paste in high performance concrete is studied.
- •
Two regression lines were established in each shrinkage vs water desorption plots.
- •
The cement-fly ash paste has highest shrinkage among the composite pastes.
- •
Increasing curing time and reducing w/c ratio reduces the shrinkage of cement paste.
