Abstract:
Clayey soil with a high degree of flexibility and a poor bearing capacity is always
problematic for structures. Montmorillonite is the main component of Nandipur,
Gujranwala clay. The activity of the soil is increased by montmorillonite. In order to
increase unconfined compressive strength and decrease the activity of clayey soil, this
study intends to utilize an environmentally friendly and economically viable material ,
that is the Ginni Pozzolan. In order to identify the soil index qualities, samples from
Nandipur Gujranwala were gathered.These included the Particle Size Analysis,
Atterberg Limits, and Specific Gravity tests. The results obtained from the laboratory
tests were used to classify the soil by USCS classification as highly plasticity clay
(CH). The Standard Compaction test was performed to obtain the maximum dry
density and the corresponding optimum moisture content. Untreated clay and clay
with additions were tested for their unconfined compression strengths. Additionally,
the activities of untreated and additive-added clay were evaluated. After the addition
of 1% Ginni pozzolan and 5% lime, soil stability has greatly increased. In addition to
laboratory testing, the UCS values of untreated clay and clay with additions were
simulated using the Abaqus programme. With the addition of 5% lime and 1% Ginni
pozzolan to clay, software also demonstrated an increase in unconfined compressive
strength.
