Evaluation of Physical Parameters of a Clay with the Incorporation of Industrial Ash Waste by Means of Variance Analysis

Abstract:

This work evaluates the incorporation of solid industrial waste such as rice husk ash, bottom ash from mineral coal and ash coming from the washing of sheep wool in Red Ceramic Mass (MRC) composed of clay. These raw materials were collected from industries in the municipality of Bagé-RS, Brazil. Percentages of 0, 5, 10, 20 and 30% of these wastes were added to (MRC) in order to reduce the environmental impacts, both by the clay extraction as well as for waste disposal. The physical tests (Atterberg limits) made with the clay, follow a normative standard. However, the tests made in the formulations served to compare the formulations’ behavior in relation to the clay. In order to verify if the tests proposed in (MRC) and if the formulations have changed significantly the investigated indexes, an Analysis of Variance (ANOVA) was performed. The results generally indicate that there are statistically significant differences, mainly regarding the Plasticity Index (PI) and the Liquidity Limit (LL), as ash was added in the formulations.
