Recycling of Steel-Making Plant Waste into Heavy Clay Ceramic- Industrial Test

Abstract

This work has as its objective to evaluate the effect of incorporation of 10 wt% of a powder waste from the sintering stage of an integrated steel-making plant in the physical and mechanical properties of bricks produced in industrial scale. Environmental tests of leaching and solubilization were performed. The results indicated that the waste slightly increased the water absorption of the ceramic and also increased in 35% its compressive strength. The sulfate parameter was above the maximum limit established by the norm for solubilization test. It was observed a strong efflorescence in the massive bricks and a smooth efflorescence in the perforated bricks.
