- Hot weather concreting
Advantages: - Makes longer work breaks e.g. overnight concreting.
- Prevents gravel, nests and bleeding
- Increases final strength up to 10%
- Gives plastic, homogeneous concrete for long distance transportation
- Expands the evolution of heat for a considerable time and thus lessens the risk of heat accumulation and strain cracks, particularly in mass concrete.
