Descripción

The objective of the present study was to evaluate the effects of industrial solid waste (whitewashmud) on geotechnical properties considering the following engineering parameters: California Bearing Ratio(CBR), Atterberg limits and Permeability test. Seven soil samples derived from Alagoinhas, Bahia - Brazil,were classified by the Transportation Research Board (TRB) system. Two were selected as having a greatgeotecnical potential classified as A-3 (0) and A-2-4 (0), whitewash mud contents 10%, 15%, 20% and 25%dry weight and medium compaction effort were studied in the laboratory testing program. The results indicatedthe soil denominated good gravel as being the most promising one, when stabilized with whitewash mud, reachingthe best results with the dosage of 20 and 25% of whitewash mud.
