RR Fire Cement Mortar
It is used for joining all types of bricks
It is high strength power cement.
RR fire cement is high temperature high alumina, air setting plasticize refractory Cement, provided to
you either in cement powder and binder liquid
In separate form or air tight packed ready to use
paste from intended for
saying ceramic fiber blanket calcium silicate blocks, Insulating bricks Fire bricks silica bricks and high alumina bricks
- Advantages
- Specification
- Higher thermal efficiency.
- the furnace by it goes and air tight Joins.
- It gives thin strong compact Joints to any brick work.
- Air setting i.e. it sets extremely hard at room temperature.
- Strength increase with increasing temperature.
- Reduce furnance troubles and ensures much longer life.
- Four time higher strength compared to fire clay/mortar.
- Welds each brick to other thus making each Joint perfect Joint.
