A concrete plasticizer specially designed for Roller Compacted Concrete (RCC)structures. Complies with ASTM C494 Type B&D

Plastiment TM 25 is used in structural and mass concrete where long setting times and improved workability are required, such as projects with:

- Large pours, to prevent formation of cold joints in RCC dams etc.

- Long travel times from the concrete plant to the site

- Difficult placing conditions and details

- High ambient temperature

Plastiment TM 25 provides the following properties:

Advantages In Fresh state

- Initial setting is delayed allowing time for proper placement and compacting new layer over the retarded RCC, without cold joint.

- Decrease the mortar of concrete bonding volume

- Increase the time available to re compacting the concrete without damaging the material. After the initial set heavy transits can dam age the newly hydrated RCC.

- Increase of the cement efficiency

- Diminish the rate of initial heat generation.

In hardened state

- Increase the mechanical strengths in any weather conditions.

- Diminish the heat generation and the cracking risk,

- Increase the density of the RCC

Dosage: 0.5 – 4.0 ltr per 100 kg of cement (depend on cement type and brand)

Compatibility: Possible to combine with all Sikament, Sika Aer, Sika Pump, Sikacrete PP1, but must be added separately to the mix and not pre-mixed prior addition.

Cement types: All Portland cement including sulfate resistant cement

Dispensing: Plastiment TM 25 is either added to the gauging water prior to its addition to the dry concrete mix or added separately to wetted concrete mix, further mixing should take place for at least 1 minute per m

Overdosing: When overdosed, setting time will be extended
