TYTRO® SA 530
Alkali-free, liquid high-performance set accelerator for shotcrete
TYTRO® SA 530 is a high-performance, alkali-free set accelerator specifically formulated to provide high early strength at low dosage rates and improve productivity by shortening the time of setting without compromising long-term strength and durability.
TYTRO® SA 530 is an easy flow, ready-to-use non–alkaline and environmentally neutral liquid suspension, and is formulated to comply with the requirements of ASTM C 1141/C 1141M, Types I /II, Grade 9, Class A.
- Efficient dosage rate – Highly active formulation for lowest dosages
- Reduced excavation downtime – Increased adhesion and faster setting
- Improved strength – Increased early age strength development without compromising later age strength
- Reduced cycle times – Quicker setting action and increased layer thickness for overhead work
- Minimum material waste – Lower rebound and dust
- Safer and healthier to handle – Non-alkaline formulation
- Robust and easy to formulate – Liquid product; easily measured and dosed
- Versatile – Wet as well as dry-mixed process
TYTRO® SA 530 is used in all shotcrete applications where high early strength is required, and especially in the following applications:
- Temporary and permanent rock support in tunnels
- Underground rock support in mining
- Slope stabilization
The dosage of TYTRO® SA 530 can vary based on the type of application, mix design, cement type and content, water-tocementitious materials ratio, temperature of the concrete, ambient temperature and temperature of the substrate on which the concrete is to be applied.
The dosage of TYTRO® SA 530 normally ranges between 3% and 8% by the total weight of cementitious materials. Overdosing (> 10%) may result in decreased final strength. Should conditions require using more than the recommended addition rates, please consult your GCP Applied Technologies representative.
GCP Applied Technologies recommends that trials be performed before use to assess and optimize dosage rates and shotcrete performance. Predetermined and tested re-entry requirements are to be measured and nominated. If further assistance is required please consult your GCP Applied Technologies Representative.
TYTRO® SA 530 is added at the nozzle. TYTRO® SA 530 is a suspension and therefore not all types of dosing pumps will work properly. Advice on dosing pumps is available from GCP Applied Technologies on request.
TYTRO® SA 530 is available in 205 litre polyethylene drums and 1,000 litre totes. In North America, TYTRO® SA 530 is also available in bulk, delivered by metered tank trucks
TYTRO® SA 530 should be stored at a temperature range of 5°C to 35 °C. It is recommended that your local sales representative be consulted prior to the use of any products that may be frozen. Performance tests should always be carried out prior to use.
TYTRO® SA 530 must be kept in closed plastic containers or closed tanks made of polypropylene, polyethylene, or PVC. Do not store in steel containers as the pH can cause corrosion which might affect the performance of the product. Containers must be tightly closed every day to avoid contact with air which can cause a chemical reaction (skin building on top and lumps which cause problems with dosing pumps).
After prolonged storage, TYTRO® SA 530 should be vigorously recirculated in the tanks by means of stirring apparatus or through recirculation before use. It can have a settlement that may not be visually detectable.
Shelf life is 6 months. Depending on storage conditions, the shelf life may be greater than stated. Please contact your local GCP Applied Technologies sales representative regarding the suitability for use if the shelf life of TYTRO® SA 530 has been exceeded.
Health and Safety
Avoid eye and skin contact and wear rubber gloves and goggles. If contact occurs, rinse with plenty of water. In case of eye contact, seek medical advice. For further information, refer to the Material Safety Data Sheet or contact your local GCP Applied Technologies representative.
TYTRO® SA 530 is compatible with all TYTRO® shotcrete admixtures. GCP Applied Technologies recommends that a suitable superplasticizer and slump life controlling admixture be incorporated into the shotcrete mix to achieve extended working life and maintain low water-to-cementitious materials ratio. TYTRO® WR high-range water-reducing and TYTRO® HC hydration control admixtures are recommended for this purpose.
Pretesting of the shotcrete mix should be performed before use and as conditions and materials change in order to ensure compatibility with other admixtures.
For use with other shotcrete admixtures systems, we recommend you to contact GCP Applied Technologies for further advice.
