Resumo: | ||||||||
In this work, characteristics of collapse of a laterítico
soil submitted to percolation of a caustic liqueur to
different concentrations are analysed. The soil comprises a
quartzitic sand with a small fraction of kaolinitic clay.
The liqueur is a caustic fluid, from an aluminium industry.
In the present study, effects of the caustic liqueur
infiltration were observed considering three aspects:
collapse, solute transport and soil suction
characteristics. This was done through an experimental
program that included physical and chemical
characterization of the soil and liqueur, special oedometer
tests to evaluate simultaneously collapse characteristics
and solute transport, and suction tests using the filter
paper method.
The results of the experimental program showed that the
soil suffers volume change in presence of water, and its
colapsivity is increased in presence of the caustic
liqueur. They also indicated that the transport and suction
parameters are affected strongly by the percolation of the
liqueur.
