Effects of Acid and Base Contamination on Geotechnical Properties of Shanghai Remolded Silty Clay

Conference paper

Abstract

Based on the laboratory tests of shanghai remolded silty clays, the effects with different concentrations of contaminations (HCl, H2SO4, NaOH) on soil plasticity, compressibility and strength characteristics were studied. The results shown that the value of the liquid limit wL, plastic limit wP, plasticity index IP, void ratio e, compression index cc and undrained shear strength cu were all increased with the increasing of concentrations of H2SO4 and NaOH. However, the contrary relationship was obtained for the HCl contaminated soil samples except the compression index cc. All of these phenomena can be explained by the ion-exchange, PH value and soil structure. The relationship between mechanical properties and plasticity parameters (cc~wL and cc~IP) of the contaminated soil samples were presented and compared with the empirical formulas for remolded clays, the results shown that the empirical formulas will underestimate the compressibility of the contaminated soil samples. However, the change of contaminated soil samples structure is not sufficient to change the relationship between cu and liquidity index IL, so the empirical formulas for remolded clay can be approximately predicted the relationship of cu and IL of these contaminated soil samples.
