Estudy of Natural and Degradation by Salt Spray of Red Ceramics Incorporated with Ornamental Rock Waste

To better study the mechanical behavior of red ceramic, the samples were degraded in salt spray equipment and exposed in environment. The salt spray equipment subjects the samples to conditions found by the sea, through the mix solutions of sodium chloride. The ceramic samples were prepared with up to 10% by mass of ornamental rock waste to dry and pressed into rectangular mold of steel. The materials were fired at temperatures of 650°C, 750°C and 850°C. After 90 days of degradation natural and 45 days in salt spray, ware analyzed the properties of ceramic material. The results of mechanical strength were compared using the Weibull distribution, before and after the degradation. Note that the material with ornamental rock waste raised the mechanical strength and didnt significantly changes the material properties after degradation.
