TruCast™ DelaySet | Powdered Concrete Retarder

TruCast™ DelaySet

Retarder

Formerly sold as DelaySet, TruCast™ DelaySet is now part of the TruCast™ family of premium powdered concrete admixtures. While the branding has changed, the trusted formulation remains the same.

TruCast™ DelaySet is a premium citric acid-based powdered concrete retarder specifically formulated to extend the working time of Calcium Sulfoaluminate (CSA) rapid-hardening cements and Ordinary Portland Cement (OPC) systems. Designed for decorative concrete professionals, architectural precast manufacturers, and advanced concrete fabricators, TruCast™ DelaySet provides greater flexibility during mixing, placement, spraying, finishing, and complex casting operations.

Rapid-hardening cement systems offer significant advantages in production speed and early strength development, but their accelerated setting characteristics can present challenges during placement. TruCast™ DelaySet helps slow cement hydration, providing additional working time while maintaining the engineered performance of your concrete mix.

Whether you're producing GFRC, self-consolidating concrete (SCC), architectural precast, concrete countertops, furniture, or custom decorative concrete, TruCast™ DelaySet gives you greater control over the setting process, allowing more time for placement and finishing without simply adding excess water.

Why Choose TruCast™ DelaySet?

Modern decorative concrete fabrication often demands additional working time, especially when producing large castings, intricate molds, or working in elevated temperatures.

TruCast™ DelaySet helps extend the workable life of your concrete, giving you additional time to mix, place, spray, consolidate, and finish before the concrete begins to set.

The result is improved production flexibility, greater consistency, and reduced stress during demanding casting operations.

Key Benefits

• Citric acid-based powdered retarder
• Designed for CSA rapid-hardening cements and OPC systems

Recommended Dosage

Typical dosage: 0.1%–0.4% by weight of total cementitious materials.

At recommended dosages, TruCast™ DelaySet typically extends working time by approximately 1–3 hours. Actual performance will vary depending on cement chemistry, mix design, ambient temperature, and project conditions.

Always perform trial batches using local materials to determine the optimum dosage for your specific application.

Mixing Instructions

For best results, disperse TruCast™ DelaySet into the batch water before adding cement and aggregates. Mixing with the batch water first promotes uniform dispersion throughout the concrete and provides the most consistent performance.

Frequently Asked Questions

Is TruCast™ DelaySet the same product as DelaySet?
Yes. TruCast™ DelaySet is the same trusted retarder formerly sold as DelaySet. Only the branding has changed as part of the TruCast™ family of premium powdered concrete admixtures.

What types of cement is TruCast™ DelaySet designed for?
TruCast™ DelaySet is specifically formulated for Calcium Sulfoaluminate (CSA) rapid-hardening cements and Ordinary Portland Cement (OPC) systems.

How much working time does it provide?
Typical dosages provide approximately 1–3 hours of additional working time, depending on mix design, cement chemistry, and ambient temperature.

Can TruCast™ DelaySet be used during hot weather?
Yes. TruCast™ DelaySet is especially useful during hot-weather casting when concrete tends to set more rapidly.

Can TruCast™ DelaySet be used with other TruCast products?
Yes. TruCast™ DelaySet is compatible with other TruCast powdered admixtures, allowing fabricators to tailor concrete performance to meet the requirements of each project.
