There are various types
of refractory castables:
- Conventional
castable
- Low
cement refractory castable
- Ultra
low cement refractory castable
- No
cement castable
According
to ASTM C401-89, based on its CaO content Refractory castables can be
classified into the following categories:
Type
|
CaO
Content
|
CC = Conventional
or Regular Castables (Konventionelle Feuerbetone)
|
CaO
= More than 2.5%
|
LCC = Low Cement
Castables
(Zementarme
Feuerbetone)
|
CaO
= 1 - 2.5%
|
ULCC = Ultra Low
Cement Castables (Ultrazementarme Feuerbetone)
|
CaO
= 0.2 - 1%
|
NCC = No Cement
Castables
(Zementfreie
Feuerbetone)
|
CaO
= Less than 0.2%
