Liquid Solutions Concrete Admixtures
SP20 is a high range water reducing superplasticiser liquid based on polycarboxylate technology. It gives water reduction of more than 20% and suits self levelling, self-compacting and low water to cement ratio precast concretes, as well as mortars, adhesives and grouts.
SP20 is a high range water reducing superplasticiser liquid. It is an extremely high efficiency anionic superplasticiser based on polycarboxylate technology, and its key function is as a high range water reducer.
SP20 has a very high deflocculation effect. Deflocculation means keeping cement particles separated rather than clumped together, and SP20 maintains this dispersed state for longer periods than conventional plasticisers. That gives high water reduction of more than 20%, very high early and final strength, and a mix that resists bleeding and segregation.
In general terms, a lower water to cement ratio gives a denser and stronger hardened concrete. A high range water reducer lets producers lower the water content while keeping the mix workable enough to place, which is why this type of admixture is widely used in self-compacting and precast work.
SP20 has applications in mortars, concretes, self levelling systems, adhesives and grouts. It is suitable for:
For an economic mid range water reducer for readymix concrete and screeds, look at SP10.
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.
SP20 should be handled in accordance with good industrial practice. Please refer to the Safety Data Sheet, available on request.
SP20 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.
