CLC series

By the reduction of the mixing amount of alumina cement, CLC shows following characteristics.

• Spalling resistance at high temperature is strengthened.
• Alkali resistant against foreign alkaline component is strengthened.

Alkali resistance test

(1) Corrosive agent:NaCl 1000℃×24Hrs

Conventional castable Matrix became weekend	CLC-A6CL49-RE No deterioration occurred in strength.

(2) Corrosive agent：Na₂CO₃　1000℃×24hrs

Super low cement castable(conventional Product) Crack occurred by volume expansion	CLC-A539-RE Little amount of Alkali penetration occurred

QD Series

QD series, developed by our own technology, have following properties compared with our conventional RE type (RE type: adding additives for preventing explosive spalling)

• Reduction of the possibility of explosive spalling
• hort dry out time becomes possible with high speed heating up
