Slow-setting additives are sometimes used to reduce the effect of hot air on concrete trapping, sometimes to prolong traction time on bulky tasks such as large concrete dams or to pump concrete over long distances or to transport ready-mixed concrete over long distances.
Properties and effects:
- Impact on concrete setting time
- Possibility of concreting in tropical areas
- Possibility of concreting in windy areas
- Possibility of concreting with long carrying distance
- Increase concrete performance time
- Increase the strength of concrete in the long run
- Prevent surface cracks
Application:
- Massive concreting such as dam construction
- Semi-bulk concreting such as very large foundations
- Concrete pumping on long distances
