Fosroc Sprayset HBP: Uses, Advantages, and Technical Specifications
Fosroc Chemicals India Private Limited produces Fosroc Sprayset HBP, a non-caustic admixture for sprayed concrete, shotcrete, and gunite. This product is distributed in India by their authorized distributor, Space Arc Engineering, which offers the complete range of Fosroc products. It is a chloride-free powder that is added to the mix to provide properties of high build and low rebound.
Uses:
Standards Compliance:
Sprayset HBP meets the requirements of ACI 506-66 and Concrete Society Specification for Sprayed Concrete.
Technical Support: Fosroc offers a technical consultation service to provide on-site support and advice on admixture selection, trial evaluation, and equipment dispensing. Technical information and guidance are available for admixtures and other products used in both fresh and hardened concrete.
Determining the appropriate dosage for Sprayset HBP to meet specific requirements should always be based on trials using the materials and conditions that will be experienced during use. Typical dosage levels for use in sprayed concrete, shotcrete, and gunite lies in the range of 2 to 5 kg/ 100kg of cement.
Application Instructions: For optimal results, it is advisable to uniformly disperse Fosroc Sprayset HBP in the dry mix, either through a bulk blend or automatic dosing equipment, while feeding the concrete mix. The moisture level of the mixture should be below 4%, and the addition of Sprayset HBP must be done immediately before use.
Effects of Overdosing:
Using double the intended amount of Sprayset HBP will have little effect on the build properties, setting time, or strength gain compared to the results achieved at the recommended dosage.
Curing :
Good curing practice should be maintained, as with all cementitious systems.
Packaging and Storage : Sprayset HBP is available in 25 kg bags and should be stored in a dry place.
Admixture selection and usage can be impacted by various factors related to concrete materials and conditions . Therefore, the performance examples provided are typical and should only be used as a reference . Trials should be made using relevant materials and conditions to determine the optimum mix design and admixture dosage to meet specific requirements. Typical performance examples from evaluation studies of Sprayset HBP are included on this datasheet. The quoted values are indicative of the results achieved and are presented to demonstrate the performance in varying scenarios. Due to the inconsistency of concrete materials, the outcomes should be considered as typical of the expected performance. Results quoted in individual examples should not be taken as necessarily directly comparable with other examples given here or results obtained elsewhere for Sprayset HBP or other products.
In summary, Fosroc Sprayset HBP is an ideal solution for high build sprayed concrete, shotcrete, and gunite, providing set acceleration and reducing rebound. Its advantages include low rebound, no adverse effect on strength, high build up with minimal slump, and safe handling. With standards compliance , technical support, and typical performance examples, it is a reliable and effective admixture that can optimize mix design and dosage to meet specific requirements .
Uses:
- Used to enable a high build of sprayed concrete, shotcrete, and gunite
- Provides set acceleration and reduces rebound
- Low rebound due to controlled set
- No adverse effect on strength
- The use of minimal slump results in faster coverage rates with a high build-up.
- Safe to handle
