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:
- Delay in concrete setting time
- Increase the strength of concrete in the long run
- Possibility of construction and implementation of concreting in tropical areas
- Possibility of construction and execution of concrete in windy areas
- Increase the performance time or workability of concrete
- Improving the solubility of concrete surfaces
- Possibility of concreting with long distance of batching to the place where the concrete is discharged from the injection tube
- Prevent the formation of surface cracks caused by shrinkage
- Reduction of cold joints due to concreting distances
Application:
- Massive and semi-bulk concreting
- Suitable for implementing projects with high concreting volume, such as dams, bridges, large-scale foundations, etc.
- Construction and transportation of concrete over long distances
- Making high-strength and impermeable concrete
- Suitable for making and executing architectural concrete
- Suitable for pumping concrete
- Suitable for the production and execution of roller concrete
