A study on permeability of soil cement / Panbarasi Govindasamy and Felix Ling Ngee Leh

Although there have been several research on engineering properties
of residual soils in Malaysia, studies on the permeability properties
of meta-sedimentary residual soils are still lacking. The objective of
this study is to determine the influence of low percentage cement on
permeability parameters of the meta-sedimentary soil. Samples of
the residual soil were taken from Bangi, Selangor. Basic properties
of soils, such as the natural water content, grain size distribution,
specific gravity, and Atterberg limits were determined. Mainly, the
coefficient of permeability of the soils both naturally and with those
anticipated in the soil-cement modification is determined by using
the Falling Head Permeability test. The results of analysis show
that the permeability of low-cement admixed soil reduce as the
quantity of cement increase. However, the addition of 10% cement
gives an increased permeability value. The generated permeability
parameters will indirectly become a guide in the preliminary soil
cement stabilisation to modify the properties of the soil to become
more like the properties of a soft rock.
