What is SP10?
SP10 is a mid range water reducing superplasticiser liquid. It is an extremely high efficiency anionic superplasticiser based on polycarboxylate technology, and its key function is as an economic mid range water reducer.
SP10 has a very high deflocculation effect. Deflocculation means keeping cement particles separated rather than clumped together, and SP10 maintains this dispersed state for longer periods than conventional plasticisers. The result is high water reduction of more than 10%, very high early and final strength, and a mix that resists bleeding and segregation.
What is a polycarboxylate superplasticiser?
Polycarboxylate ethers are a modern family of superplasticisers. In general terms, they attach to cement particles and push them apart, so a concrete can reach the same workability with less water, or greater workability at the same water content.
Where is SP10 used?
SP10 has applications in screeds and concretes, including:
- Readymix concrete, where it is a highly effective and economic plasticiser
- High slump concretes
- Screeds
- Mixes made with OPC and blended cements, with which it has good compatibility
For higher water reduction, or for self levelling, self-compacting and low water to cement ratio precast concretes, look at SP20.
How to use SP10
- Ideally mix SP10 in with the initial hydration water.
- Add this to the moist components at the early stages of batch preparation.
- Mix for a minimum wet mixing time of 2 to 3 minutes. Activation in the wet state is rapid.
Typical dosage rates are in the order of 0.5% to 0.9% by weight of cement. This is a guide only. Evaluation trials are recommended to establish the optimum dosage for your materials, so confirm your dose with trials and with our technical support team.
SP10 should be handled in accordance with good industrial practice. Please refer to the Safety Data Sheet, available on request.
Packaging, storage and shelf life
SP10 should be stored correctly in a dry environment between 5°C and 35°C. It has a shelf life of 2 years when stored correctly. For current pack sizes and delivery options, please contact UKCP.
