Expansive Cement
Summary
Expansive Cement - is cement which expands on hydration.
Technical Information
There are two types of expansive cement, which expand at different magnitudes:
- When the magnitude of expansion is small, the cement is known as ‘shrinkage compensating’
- When the magnitude of expansion is large, the cement is known as ‘self stressing’ and can be used for the production of chemically pre-stressed concrete elements.
