EXPAND THE POSSIBILITIES FOR CONCRETE PLACEMENT, USE AND RECYLCING

Through innovative specialty admixtures, Sika offers cost effective solutions to address challenges with production, placement, and concrete returned to the plant.

Returned Concrete Treatment
Surface Enhancement & Finishing

The appearance of an exposed concrete surface is ultimately how concrete is judged, regardless of quality. Whether removing the appearance of unsightly bugholes, using surface retarder to create an exposed aggregate appearance, or curing concrete for maximum quality, Sika has the right products to enhance final concrete surface.

SikaControl® FD-100

INTEGRAL FRESH CONCRETE DENSIFIER
SikaControl® FD-100 increases density of freshly mixed non air entrained concrete. SikaControl® FD-100 is suitable for interior flooring applications with a hard trowel finish. Use of SikaControl® FD-100 results in dense concrete with reduced amount of pinholes, open pores and other surface defects.    SikaControl® FD-100 helps to achieve concrete properties as described in the ACI 302.1R-15 - Guide to Concrete Floor and Slab construction. SikaControl® FD-100 provides the following advantages:
  • Concrete with minimum surface defects
  • Reduced risk of blistering and delamination issues
  • Easy to finish polished surface
  • Improved concrete aesthetics
  • Improved concrete uniformity and reduced risk of claims related to elevated air content
  • Improved concrete durability
Viscosity Modifiers & Rheology Enhancement

Concrete placement characteristics are a function of the design and proportioning of cement paste, aggregates, and chemical admixtures. During pumping or placement, the paste rheology is a critical performance factor. The use of rheology/viscosity modifying admixtures (VMA) increases the cohesiveness of concrete, thereby reducing the risk of segregation.

 

Sika’s Viscosity Modifying Admixtures meet relevant industry standards per application, such as ASTM C-494, Type S or CRD-C661-06. See product data sheets for details.

Underwater Concreting

Sikament®-100 SC

Anti-Washout Admixture
Sikament®-100 SC reduces or eliminates the need to dewater underwater construction sites before concrete construction can take place. Concrete can be placed by pump or tremie directly into areas covered by water. Sikament®-100 SC maintains the concrete matrix integrity during high slump placements and reduces washout from the surface during curing.
  • Reduce or eliminate dewatering costs associated with underwater construction.
  • Concrete is easy to pump and flows readily into available spaces.
  • Segregation and dilution are reduced, in-place compressive and bond strengths are significantly increased.
  • Laitance on concrete surface caused by cement paste washout during curing is reduced or eliminated.
  • The active slump life of the concrete is doubled without extended delays in setting time.
Flowable Fill

Flowable fill is a self-compacting, flowable concrete used as an economical fill or backfill material. Available as a powder or liquid, Sika Lightcrete products are an easy and economical solution for flowable fill production.
