Advance Castables (Low Cement)
Deflocculated casts are made from deflocculating factors and ultra fine particles like reactive alumina,
microsilica, fine calcind alumina along with high alumina, cement as basic factor of binding system.
:Types
Medium cement: CaO content is >2.5%
Low cement: CaO content is 1.5 -2.5
Ultra low cement: CaO content is < 1.2%
Non –cement: CaO content is <0.3%
:Features
Favorable reduction of mixing water and consequently results in lower porosity.
Higher fired strengths even at cured prioud compare to conventional class.
Greater chemical and erosion resistance against aggressive atmosphere, moltem metals and slags.

:Typical Application

Highly corrosive atmosphere reaction kiln
Main gas header of methanol lining
Electrical arch roof
Walking beam
