Over the past decade, polycarboxylate superplasticizers for concrete (PCE) have become an example of the successful implementation of new technology in the production of concrete.

Having started their way in the production of self-compacting concrete, they gradually penetrated into the field of precast concrete.

Step by step, these additives began to be actively used by manufacturers of ready-mixed concrete and, last but not least, by manufacturers of precast concrete products.

Due to the specific action of PCE.plasticizers, concrete producers can obtain products with improved characteristics and optimize the production process, both from an economic and environmental point of view.

Depending on the chemical structure of polymers and how they work, PCE polycarboxylate superplasticizers for concrete can be designed specifically for specific applications.

In the production of precast concrete, polymers with long side chains produce a product with high early curing rates.

The backbone of the polymer can be optimized by modifying the electrical charge density to achieve maximum performance (maximum long-term) workability of ready mixed concrete mixes.

To fully develop its properties in concrete, the PCE polycarboxylate superplasticizers for concrete must be compatible with other components of the concrete mixture.

The chemical composition of the cements used in the production of the mixture, and in particular their sulfate content, can significantly affect the effectiveness of additives.

The type of filler sand can also affect the performance of the polycarboxylate superplasticizers for concrete.

Due to the chemical structure, the polymer particles are easily incorporated into the clay layers if the clay is present as an impurity in the sand, and thus can lose effectiveness significantly.

Knowledge of the properties and specific behavior of PCE polycarboxylate superplasticizers for concrete allows manufacturers to fully exploit the benefits of PCE technology.
