Sika® ViscoCrete®-510 P
Sika® ViscoCrete®-510 P is a high-performance superplasticizer and water reducer in powder form, based on Sika® ViscoCrete® polycarboxylate (PCE) polymer technology.
- Universally applicable for all binder systems
- Strong water reduction
- Short mixing times due to fast adsorption
Usage
Sika® ViscoCrete®-510 P is formulated for use in cementitious dry mortar or dry concrete applications. Especially suitable for cements with high C3A, sulphate and alkali content but also for a wide range of calcium sulphate or ternary binder systems. Sika® ViscoCrete®-510 P is universally applicate and can be used for the production of:- Calcium sulphate and cement-based screeds and self-levelling screeds and underlayments
- Non-shrink grouts, and anchor grouts, tile adhesives injection an repair mortars
- Building plaster, render, stucco, bonding/filling compound, molding plaster, dental & medical plaster
- Self-levelling and self-compacting concretes with low w/c-ratio
Advantages
Sika® ViscoCrete®-510 P is adsorbed onto the surface of the binder particles and due to repulsive forces from the effect known as steric hindrance, the solid binder particles are very effectively dispersed in the mix.The benefits of Sika® ViscoCrete®-510 P include, but are not limited to the following:
- High water reduction at low dosage, resulting in shorter drying times, higher densities and strengths
- Greatly reduced processing and compaction efforts due to very good flow and self-levelling behaviour
- Particularly high activity in systems with pH-value > 12
- Reduced mixing times due to fast adsorption
- High initial flow, long slump life and processing time
- Improved shrinkage and creep behaviour
- Low influence on hydration, resulting in low activator/accelerator consumption
- Compatible with cements with high C3A, sulphate and alkali content
- Compatible with other additives (e.g. fruit acids, such as citric acid)
- Free of formaldehyde and ammonia

Application
Compatibility
Sika® ViscoCrete®-510 P may be combined with most existing redispersible powerds accelerators, retarders and other additives used in dry-mortar applications. In order to achieve an optimal effect with respect to initial liquefaction and slump keeping, the combination with another Sika ViscoCrete Powder is possible.
Important: Always conduct trials before combining products in specific mix designs and contact our Technical Services Department for any additional information and advice concerning specific combinations with other products.
Dispensing
Sika® ViscoCrete®-510 P is added to the dry mix. For optimum utilisation of the high water reduction capability, a minimum wet mixing time of 30 seconds is recommended for the mortar before use.
Recommended Dosage
Depending on the application the dosage rate of Sika® ViscoCrete®-510 P varies from 0.05 - 0.5 % of the binder weight. At high dosage and/or at low temperatures Sika® ViscoCrete®-510 P can also cause retardation. At too high dosage, the mixture may also tend to repet water or to separate.
Note: Preliminary testing is required to determine the excat dosage for your specific conditions. Please contact our Technical Services Department for more information and advice.
