In most cases, refractory aggregates make up 75% + of the refractory monolithic product, and  therefore the quality of the aggregate directly influences the behaviour of the refractory product at high temperatures. High impurities may results in untimely failures or lower product performance. 

At IRS we have fully operational and well engineered quality monitoring systems that ensure materials go through multiple sorting and separation processes that remove impurities to the most minimal concentrations possible. Our recycled refractory aggregates go through these multiple checks of quality control to minimize the undesired contaminations. Reach out to us and we will provide you with product data sheets for each product.
