The wet precast method offers numerous advantages in terms of quality, efficiency, and consistency compared to traditional on-site concrete casting. Common applications of wet precast concrete include wall panels, beams, columns, slabs, architectural cladding, and various precast structural components. Admixtures are often employed to enhance the performance, workability and characteristics of wet precast concrete.

Workability Solutions:

Workability in precast concrete refers to the ease with which the concrete can be mixed, placed, and finished. Achieving the right workability is crucial to ensuring that the concrete can be properly shaped and compacted within the mould or formwork. Superplasticizers are high-range water-reducing admixtures that can significantly improve the workability of concrete without increasing the water content. They are particularly useful for wet precast concrete because they allow for better flow and self-compaction.

MasterGlenium ACE 466 - High-range, enhanced workability water-reducing admixture with rheology control and added retention benefits for precast concrete.

MasterGlenium ACE 474 - High-range, enhanced workability water-reducing admixture with longer open life for precast concrete.

MasterGlenium ACE 499 - High-range, enhanced workability water-reducing admixture with faster setting and early strength gains for precast concrete.

Accelerating Solutions:

Accelerating the production and curing of precast concrete can help expedite construction projects and improve efficiency. Precast accelerating admixtures are specifically designed to speed up the curing and setting time of concrete. These admixtures can be added to the mix during batching to achieve faster strength development.

Master X-Seed 100 - Unique hardening accelerator to enable increased productivity at all temperatures which reduces hardening times, CO2 emissions & therefore lower energy costs.

MasterSet AC 555 - Set accelerating admixture for concrete especially at low temperatures.

Advanced Rheology Solutions:

Achieving the desired rheology (flow and deformation behaviour) is crucial for applications such as self-compacting concrete, high-performance concrete, structural components and architectural elements. Superplasticizers and viscosity-modifying admixtures are crucial in controlling the rheology of concrete. Superplasticizers can reduce water content while maintaining workability, while viscosity modifiers can enhance or reduce the fluidity of the mix.

MasterEase 5200 - High range water reducing admixture for precast concrete, with superior rheology, reduced mixing time and improved consistence retention performance.

MasterMatrix 233 - High range water reducing admixture for concrete with unique rheology enhancing benefits.
