Concrete accelerators are essential admixtures designed to speed up the setting and hardening process, allowing for faster construction timelines and improved operational efficiency.
They are particularly valuable in cold-weather applications, where lower temperatures can delay hydration and slow down strength development. Accelerators also help reduce mould-strike times, enhance early strength gain, and improve surface finishes — especially in precast and ready-mix environments.
Why Are Accelerators Used in Concrete?
Accelerators modify the cement hydration process, enabling concrete to gain strength more rapidly without compromising long-term durability. They are widely used in applications where time-sensitive production cycles or early-age performance are critical, including:
- Precast concrete – Reduces formwork turnaround time, increasing productivity
- Cold-weather concreting – Counteracts delayed hydration caused by low ambient temperatures
- Structural components – Delivers reliable early strength while maintaining long-term integrity
Oscrete’s Accelerator Admixture Range
Oscrete offers a targeted range of accelerator admixtures designed to support precision strength development and optimise concrete mix performance across various applications.
Betacast NCA & Betacast XLR – Non-Chloride Accelerators
- Betacast NCA is a high-performance non-chloride accelerator suitable for concrete, screeds, and mortar.
- Betacast XLR enhances compaction and early strength, ideal for semi-dry and wet cast concrete, helping speed up processing cycles.
Colourplas 334C – Calcium Chloride Accelerator for Low-Slump Concrete
Formulated to boost early strength in dry/semi-dry concrete, Colourplas 334C also improves workability in low-slump applications. It offers:
- Rapid setting for efficient paving and block production
- Improved mix cohesion, ensuring consistency across production runs
With Oscrete’s technical expertise and innovative admixture solutions, our accelerator range supports efficient, high-performance concrete production. These products help manufacturers meet evolving sustainability targets — including 2030 and 2050 carbon reduction goals — without compromising mix integrity or production timelines.
