SikaPlast® RMC 50
set retardation properties
Sikaplast RMC 50 is a high performance
concrete plasticiser and water reducing agent.
Unlike conventional Iignosulphonate plasticisers
it possesses the ability to increase early and
ultimate strengths even at constant water
cement ratios.
Sikaplast RMC 50 is designed to
optimise hydration of the cement paste, subject
to the mix design. When compared to a control
concrete 28 days strengths are achievable in 7
days and similarly 7 days strengths are achieveable within 3days.
Sikaplast RMC 50 is a versatile product
which can be utilised throughout a varying range
of temperatures. It can be used as a standard
plasticiser in the low dosage range through to a
powerful retarder at the high dosage range.
- Highly effective over wide range of cement contents
- Higher early and ultimate strengths
- Low dosage
- Improves workability whilst at the same time
- increasing compressive strength
- Permits water reduction, in the region of 10%
- to 15%
- Increases impermeability and durability
- Reduces placing problems in hot weather
- concreting by improving workability and
- workability retention
- Improves surface finish, pumpability and
- trowellability
- Enables significant economies in mix design
- to be achieved thereby saving cement
