In precast concrete , production speed is a decisive competitive factor. Precast additives make it possible to accelerate the development of initial strengths, reduce formwork times and optimize production cycles in industrial plants.
Prefabrication and production cycles: why time matters
In the precast concrete sector, the management of production times is one of the most strategic aspects for the competitiveness of plants. Reducing the maturation time and anticipating the formwork phase allows you to optimize the use of formwork and increase the number of daily production cycles.
In contrast to in-house structures, productivity in this context depends to a large extent on how quickly the moulds can be freed and reused for a new casting. Beams, columns, panels and floors are produced in the factory and transported to the construction site: every hour saved translates into a direct advantage on costs and production capacity.
Reducing formwork times concretely allows you to:
- increase the number of daily production cycles;
- improve the use of formwork;
- optimize the management of storage spaces;
- reduce the overall costs of the production process.
To achieve these goals, however, it is necessary that the concrete develops adequate initial mechanical resistance in a very short time.
The contribution of chemical admixtures for concrete
Precast admixtures are chemical formulations designed to modify the behavior of fresh concrete and speed up cement hydration processes. EKAN develops specific solutions for this sector, designed to meet the needs of the most intense production cycles.
Among the main types used in prefabricated plants:
Setting and hardening accelerators
Accelerating admixtures promote the rapid development of initial strengths, allowing the stripping phase to be anticipated without compromising the final performance of the concrete.
Next-generation superplasticizers
Superplasticizers improve the workability of the mixture and reduce the water/cement ratio, helping to increase mechanical resistance in the first hours of maturation.
Additives for the rapid development of heating elements
Specific formulations for rapid production cycles that combine accelerating effects and optimization of the compaction of the conglomerate, designed for production-intensive plants.
Synergy with accelerated ripening systems
In prefabrication plants, additives are often used in combination with accelerated curing systems, such as steam maturation chambers or heated formwork. These technologies make it possible to control temperature and humidity during the first hours of maturation, promoting faster hydration of the cement.
The synergy between additives and controlled maturation makes it possible to:
- quickly reach the resistances necessary for formwork;
- reduce the time spent in the formwork;
- stabilize the quality of the products produced.
Productivity and quality of the product: a possible balance
The correct use of additives does not only result in an increase in production speed. A well-designed blend also improves the quality of the finished product, with benefits that affect the entire supply chain.
Among the main advantages:
- better concrete compaction;
- more regular and defect-free surfaces;
- reduction of the risk of porosity or cracking;
- greater uniformity of mechanical performance.
