Kimia Ceram Zarin's Refractory Setting Accelerator is a specialized additive for accelerating the setting of refractory castables and mortars. By enhancing the hydration reaction of calcium aluminate cements (CAC), it significantly reduces both initial and final setting times. This enables faster demolding, quicker commissioning of refractory linings, and reduced kiln downtime for repairs. Available in ready-to-use liquid form, it is compatible with various alumina and alumina-silica refractory systems.

How does a refractory accelerator differ from a standard concrete accelerator?
Refractory accelerators are formulated for calcium aluminate cements (CAC) and remain stable at high temperatures, whereas standard concrete accelerators are designed for Portland cement and lose effectiveness above 500°C.
What is the typical dosage of refractory accelerator?
Typical dosage ranges from 0.5% to 3% by weight of calcium aluminate cement, depending on castable type, ambient temperature, and desired setting time. Laboratory testing is recommended before bulk application.
