Introduction High Castable Refractory Cements

High Castable Refractory Cements give furnaces, kilns and boilers a tough, heat-proof lining. The castable mixes with water and sets into a dense, monolithic block. Moreover, the cement keeps its strength at temperatures up to 1600°C. Workers pour, trowel or pump the material into any shape, so complex linings take less time. Factories in Bangladesh use it to repair brick kilns, boiler walls and foundry ladles. The low cement content reduces cracks during the first heating. Besides that, the high alumina base resists slag and chemical attack. Each 25 kg bag arrives in a moisture-proof pack, and astzbd delivers it across Bangladesh. You get a reliable lining material that cuts shutdowns and repair costs. Buyers also gain steady quality from batch to batch. The material bonds well with firebricks and keeps the lining tight and stable. As a result, skilled crews finish most jobs in a single shift.

Frequently Asked Questions / FAQ High Castable Refractory Cements

1. What temperature do High Castable Refractory Cements handle?
   They handle continuous service up to 1600°C.
2. How much water should I add?
   Add 8–10% water by weight. Mix until the castable flows evenly.
3. How long does the castable take to cure?
   The castable sets in 24 hours. Dry it slowly at 110°C before the first full firing.
4. Can I use it to repair old firebrick walls?
   Yes. Clean the surface first, then apply the castable in layers.
5. How should I store the bags?
   Keep the bags in a dry, covered place away from moisture. Use them within 6 months
