Influence of amang (Tin Tailing) on geotechnical properties of clay soil (Pengaruh amang timah terhadap sifat geoteknik tanih lempung)
Amang or tin tailing is commonly found in the vicinity of disused mining area and responsible in downgrading the water quality, landscape and mechanical behaviour of soils.

Amang or tin tailing is commonly found in the vicinity of disused mining area and responsible in downgrading the
water quality, landscape and mechanical behaviour of soils. It was generated from extraction process of separating
valuable metal from particular ore. This paper presents the geotechnical characteristics of amang-contaminated
clay soil. The geotechnical properties of uncontaminated soils were studied in order to compare to that of amangcontaminated
soils. The base soil used in this study represents completely weathered horizon of metasedimentary
rock. Meanwhile, tin tailing sample was taken from the disused mine at Sungai Lembing, Pahang. The geotechnical
characterisations of base soil and contaminated soils were determined based on consistency index, compaction
behaviour, hydraulic conductivity and undrained shear strength (UU tests). Contaminated soil samples were prepared
by adding 5, 10 and 20% of tailing, based on dry weigh of the studied base soil. The results from the particle size
distribution analysis showed that residual soil from metasedimentary rock comprised 42.6% clay, 32.2% silt and
25.2% sand whilst tailing was dominated by 98% of sand fraction. XRD analysis indicated the presence of quartz,
kaolinite and muscovite minerals in the studied soil. The specific gravity of soil used is 2.67 and the pH is 3.88.
Tailing found to have higher specific gravity of 3.37. The consistency index of contaminated soils showed that liquid
limit, wL and plastic limit, wP decreased with the increase in the percentage of tailing added to the soil samples.
The value of maximum dry density, ρ dry max increased while optimum moisture content decreased due to the increase
in tailing content in soil sample. The permeability of contaminated soil also increased with the increase in tailing
contents ranged from 19.8 cm/hr to 23.8 cm/hr. The undrained shear strength, Cu, of contaminated soil decreased
from 646 kPa (5% of tailing) to 312 kPa (20% of tailing) suggesting that the presence of tailing has influenced the
geotechnical properties on the studied soil. |
