Abstract
The present study mainly focuses to explore the possibilities of using natural materials
like Tamarind Kernel Powder (TKP), Egg Shell Powder (ESP) and so on for soil
improvement on problematic clays. However, the current study aims to evaluate the
potential of adoption of Tamarind Kernel Powder (TKP) particularly for soil
improvement on construction waste soil. Tamarind Kernel Powder (TKP) has been
evaluated for its potential of adoption in soil improvement by investigating and
comparing the geotechnical properties of construction waste soil before and after
addition of Tamarind Kernel Powder (TKP). So, several parameters including specific
gravity, shear strength, dry density and moisture content have been selected for
comparison through laboratory tests such as the Specific Gravity Test, Direct Shear Test
and Compaction Test.
The addition of 15% of Tamarind Kernel Powder (TKP) to construction waste
soil resulted in decrease in specific gravity of the construction waste soil from 2.17 to
1.85. The addition of 10% of this natural material also resulted in decrease of shear
strength of the construction waste soil generally, with highest value of 75.440°for angle
of internal friction and lowest value of 19.955 kN/m2 for cohesion. Furthermore, the
maximum dry density of construction waste soil decrease from 1711.91 kg/m3 to
1615.51 kg/m3 but the optimum moisture content (OMC) of the construction waste soil
increase from 9.72% to 9.99% when added by 15% of Tamarind Kernel Powder (TKP).
