Sika Rapid 2

Non-alkaline accelerator for concrete setting and hardening.

Description

Sika Rapid 2 is an additive that accelerates the setting and hardening of concrete.

---

Application

Sika Rapid 2 is used as an effective accelerator for setting and hardening, providing high early strength of concrete. Sika Rapid 2 is applied in:

– Production of precast concrete, including prestressed concrete;
– Low temperatures to achieve the required strength.

---

Advantages

– No negative impact on the properties of superplasticizers and other additives;
– No negative impact on the final strength of concrete;
– Increased turnover of formwork and molds;
– High strength gain of prestressed elements;
– Reduced curing time;
– Ability to perform concrete works at low temperatures.

Sika Rapid 2 does not contain chlorides or other substances that cause corrosion of reinforcement, so this additive can be used without any restrictions for reinforced concrete structures, including prestressed ones.
