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-alkali and is formulated to comply with the requirements ASTM C 1141/C 1141M, Types I/II, Grade 9, Class A.
TYTRO® SA 530 is used in all shotcrete applications where high early strength is required, and especially in the following applications:
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 4% 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 local GCP representative.
GCP recommends that trials be performed before use to assess and optimise 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 local GCP representative.
| Form | Liquid |

Shelf life is 3 months. Depending on storage conditions, the shelf life may be greater than stated. Please contact your local GCP representative regarding the suitability for use if the shelf life of TYTRO® SA 530 has been exceeded.
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 on request.
TYTRO® SA 530 is available in 205L polyethylene drums and 1,000L totes. TYTRO® SA 530 is also available in bulk, delivered by metred tank trucks on request.
TYTRO® SA 530 should be stored at a temperature range of 5ºC to 35ºC. It is recommended that TYTRO® SA 530 be kept out of direct sunlight.
TYTRO® SA 530 must be kept in closed plastic containers or closed tanks made of 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.
TYTRO® SA 530 is compatible with all TYTRO® shotcrete admixtures. GCP recommends that a suitable superplasticiser 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.
