Green Refractory Bricks Produced in Iran by Using Ceramic, Fiber Waste

“Considering that our research specially focuses on the use of waste materials in concrete and the optimization of plans for mixing the third-generation concretes or geopolymer composites, we decided to visit some brick-producing factories to observe closely their production cycle. The mentioned visits enabled us to assess the existing problems and the feasibility of using heat-resistant composites without the need for a high degree of curing,” Babak Behforouz, the director of research and technology department of the Islamic Azad University’s Dehaqan branch, told ANA.

Noting that studies showed that using aluminum-silica base waste materials as the base refractory in the production of third generation bricks is possible, he added, “After conducting a complete laboratory SICA, we came to the idea of producing green fireproof geopolymer bricks.”

“In this project we used waste materials like waste tile powder remaining from construction materials. In the meantime, since one of our goals in this project was to increase the flexural strength of bricks, we utilized fibers as the best material to this end,” Behforouz said.

Refractory materials are those that can withstand high temperatures without the heat damaging their structure, resistance, or thermal conductivity.

In the case of bricks, the chemical composition of refractories is different from that of regular bricks, which also influences their color and thermal conductivity.
