10. Conclusion

The use of admixtures in the concrete industry has revolutionized concrete technology. They enable :

• control of the workability of the concrete to overcome problems caused by delays in transport or processing;

• pump application;

• faster formwork rotation;

• limited ripening time, etc.

The introduction of admixtures on the market has led to a new generation of concretes (more durable, virtually porosity-free) and greater ease of use than conventional concretes.
