Tempo High-Early Age Strength
Tempo High-Early Age Strength is designed to achieve early-age strength to allow reduced stripping and re-shoring times. This series of mixes is available to achieve target strength at 24 to 72 hours.
|HOURS TO STRIPPING STRENGTH*||ULTIMATE SPECIFIED STRENGTH||EXPOSURE CLASS|
|20 MPa @ 72 hours||35 MPa @ 28 days||N|
|20 MPa @ 48 hours||40 MPa @ 28 days||N|
|20 MPa @ 36 hours||45 MPa @ 28 days||N|
|20 MPa @ 24 hours||50 MPa @ 56 days||N|
|20 MPa @ 24 hours||55 MPa @ 56 days||N|
|20 MPa @ 48 hours||35 MPa @ 28 days||C-1|
|20 MPa @ 24 hours||40 MPa @ 28 days||C-1|
* CSA A23.1-09 states a minimum curing temperature of 10 degrees Celsius.
- Columns and walls
- Reduces stripping time
- Earlier serviceability
- Reduces drying time (flooring application)
