Sikament®-475

Multi Range Water Reducing Admixture

Sikament®-475 is a multi range water reducing and slump retaining admixture utilizing Sika’s ViscoCrete® Technology. Sikament®-475 is designed to meet the requirements for ASTM C-494 Types A and F.

  • Enables water reduction.
  • Improves workability retention without significantly delaying the set time of concrete.
  • Improves early and later age strength and durability of concrete.
  • Minimizes potential for bleeding and segregation in concrete.
  • Improves pumpability and reduces stickiness in concrete.
  • Improves finishability and surface appearance of concrete.
   Sikament®-475 does not contain calcium chloride or any other intentionally added chlorides and will not contribute to corrosion on steel reinforcement present in the 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 any applications including slabs, paving, footings, wall panels, beams, columns and other concrete elements.

Application

Application Information

Mixing

For best plasticizing results, Sikament®-475 should be added directly to freshly mixed concrete in the concrete mixer 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 80-100 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 Sika admixtures. If used in combination with certain Sikament® high range water reducers, it may affect the plastic properties of fresh concrete. Please contact your local regional office or technical service department at 1-800-933-7452 for further information.

  

Combination with Pozzolanic Materials: Sikament®-475 is well suited for use with pozzolanic materials such as fly ash, slag, silica fume and metakaolin.
Consumption

Recommended Dosage

Dosage rates will vary depending on the material used, ambient conditions and the requirements of a specific project. For general concreting applications, Sika recommends a dosage rate between 3-15 fl. oz. / 100 lbs. (200–980 ml / 100 kg) of cementitious materials. If maximum water reduction is required, dosage up to 20 fl. oz. / 100 lbs. (1300 ml / 100 kg) or above 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. In this case please contact your local regional Sika office or Sika Technical Service department at 1-800-933-7452 for further information.
