TAKE CONTROL OF YOUR CONCRETE
Sika’s set controlling admixtures allow producers and contractors to manage the consistency and set times of concrete during extreme temperatures and the most demanding situations. Whether you need to pump concrete for over a mile, or winter’s chill is doing its best to keep you from placing concrete, Sika can help deliver quality and consistency for ready mixed, precast, and shotcrete applications.
Sika has a full range of chloride and non-chloride accelerators known as SikaSet that decrease the set time of concrete.
Strength / Hardening Accelerating Admixtures help to increase the early strength of concrete without affecting initial workability. This product type is especially useful in applications for repair, Department of Transportation, and precast concrete applications without the need for changes in cement. Sika® Rapid Series meets the requirements of ASTM C-494, Type C accelerating admixture.
Sika Plastiment series extends the setting time of concrete allowing time for proper placement and finishing without cold joints.
Hydration controlling admixtures control the hydration rate of cement, rather than just delaying set time. In doing so, set times are significantly more predictable, dosing is more consistent, and concrete durability is unaffected. For applications ranging from underground tunneling and mining to managing the effects of long delivery times and heat, hydration controlling admixtures are a versatile solution to control concrete during its plastic state. SikaTard® Series of admixtures meets the requirements of ASTM C-494, Type B and Type D admixture.
The Sika Sigunit line of shotcrete accelerators are high performing products for both the dry and wet spraying process. They provide a distinct reduction in rebound and facilitate overhead spraying.
