It is a product of concrete additives which, after being added to concrete, causes a delay in the setting time of cement and slows down the progress of the hydration reaction.
Properties and effects:
Delay in setting of concrete
Possibility of concreting in windy areas
Prevent surface cracks
Increase the strength of concrete in the long run
Compatibility with Portland cement types
Carrying concrete over long distances
Pumping concrete over long distances
Bulk concreting such as dam construction projects
Ready-mixed concreting with high transport time
Concreting that has a slow and gradual setting of the desired concrete
The amount of concrete retardant consumption varies depending on the ambient temperature, wind intensity, type of cement used and the time required to delay the setting time of concrete and should be determined through test samples in the workshop.
This amount can be in the range of 0.1 to 8.1% of the weight of cement consumed.
Method of Use:
In order to achieve the highest efficiency, first it is mixed with water and then other components are added, and after complete mixing, concreting begins. It should be noted that if other additives are used, the additive must be added to the mixture completely separately and not previously mixed.
