As shown in the figure, concrete retains its consistency very well at 20°C for more than 90 minutes as required; 1 day later, the compressive strength of the concrete was 8.7 N/mm2, i.e. was already sufficient to remove the formwork. Compared to conventional SP, it is possible to produce ready-to-place concrete in the factory.

Additional adjustment of the consistency of concrete for its placement on the construction site, often by insufficiently trained personnel, which could previously lead to errors, is no longer required.

Thus, the cause of errors is eliminated: it occasionally happened that water was added to the concrete at the place of laying to obtain the consistency necessary for laying the concrete, or the concrete was laid too hard. As a result, for example, separation of the mixture occurred, strength decreased, the quality of the finished concrete surface deteriorated, or the concrete durability index fell – a problem that is well known to everyone.

For hydrotechnical concrete, which is used in the production of concrete products such as bridge structures, concrete pipes, culverts and tiles, pce polycarboxylate superplasticizer have also been successfully used for several years. Due to their special properties, PCEs can be used to significantly improve the compactibility of concrete and thus to optimize the production process and concrete composition, for example by reducing the cement content.
