Sikament®-475
Sikament®-475 is a multi-range water reducing admixture utilizing Sika’s ViscoCrete®Technology.
- Water reduction
- Improves workability retention without significantly delaying the set time of concrete
- Improves the mechanical finishability of concrete
- Minimizes potential for segregation in concrete
- Improves pumpability and reduces stickiness in concrete
- Improves finishability and surface appearance of concrete
Usage
Sikament®-475 is recommended for use in the production of conventional ready mixed concrete. Addition of Sikament®-475 to concrete enables water reduction and workability retention. Concrete containing Sikament®-475 can be used for almost any application, including slabs, paving, footings, wall panels, beams, columns and other concrete elements.Advantages

Application
Mixing
Mixing
For best plasticizing results, Sikament®-475 should be added directly to freshly mixed concrete in the concrete mixer or at the end of the batching cycle. Sikament®-475 may also be dispensed as an integral material during the regular admixture batching cycle, or into freshly mixed concrete in a ready-mix truck at the concrete plant or job site. To optimize the superplasticizing effect, Sika recommends that the combined materials be mixed for 60-100 revolutions, either in the concrete mixer or in the ready-mix truck.
Combination with other admixtures: Sikament®-475 is highly effective as a single admixture or in combination with other admixtures in the Sika System. If used in combination with certain Sikament® high range water reducers, it may affect the plastic properties of fresh concrete. Contact your Sika Canada Technical Sales Representative for further information.
Combination with pozzolanic materials: Sikament®-475 is particularly well suited for use with pozzolanic materials such as fly ash, slag, silica fume and metakaolin.
Recommended Dosage
For general concreting applications, the recommended dosage is 195-980 mL/100 kg cementitious materials. Dosage rates will vary depending on the material used, ambient conditions and the requirements of a specific project.
If maximum water reduction is required, dosage up to 1300 mL per 100 kg of cementitious materials may be used. In this case, delayed setting times may occur. Dosage rates outside the recommended range may be used where specialized materials such as microsilica are specified, extreme ambient conditions are encountered or unusual project conditions require special consideration. Contact your Sika Canada Technical Sales Representative for further information.
