ONE OF CONCRETE'S MOST SIGNIFICANT ADVANTAGES IS ITS WIDE RANGE OF POSSIBILITIES FOR PLACEMENT AND USE
The ability for a concrete producer to address these opportunities makes them not only more helpful to their customers, but more profitable in the marketplace. Mixes which were previously a challenge, such as underwater concreting, creating pumpable mixes, increasing surface quality and aesthetics, or creation of low-strength flowable fill at an economical price point, are all easily addressed with Sika.
Through innovative specialty admixtures, Sika provides value to concrete producers, contractors, and ultimately the owner.
Concrete placement characteristics are a function of the design and proportioning of cement paste, aggregates, and chemical admixtures. During scenarios such as pumping or placement underwater, the paste viscosity is an especially critical performance factor. The use of a viscosity modifying admixture (VMA) increases the cohesiveness of concrete, thereby reducing the risk of segregation.
Sika’s Viscoscity 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.
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.
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.
