1. Refractory Aggregate Description

Refractory aggregate refers to the refractory granular material that acts as a skeleton in the particle size composition of the refractory material. They are made by calcining, crushing, or artificial synthesis of various raw materials, and granular materials with a particle size greater than 0.088mm. Aggregate is the main material in unshaped refractory materials, generally accounting for 60%-75% of the total composition.
