%X Artificial cementation </span><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\">is a method commonly used
to enhance and improve soil properties. This paper investigates the effect of
using different amounts of cement on soil strength parameters and soil </span><span style=\"font-family:Verdana;\">bearing capacity, using the finite element method.
Experimental tests are conducted on soil samples with different amounts of
Portland cement. A 2-D numerical model is created and validated using the
numerical modelling software, COMSOL Multiphysics 5.6 software. The study finds
that the cohesion, and the angle of the internal friction of the soil samples
increase</span></span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:Verdana;\">significantly
as a result of adding 1%, 2%, and 4% of Portland cement. The results
demonstrate that the stresses and strain under the strip footing proposed
decrease by 3.24% and 7.42%. Moreover, the maximum displacement also decreases
by 1.47% and 2.97%, as a result of adding cements of 2% and 4%. The bearing
capacity values obtained are therefore excellent, especially when using the 2%
and 4% cement. The increase identified is due to the increased values of the
bearing capacity factors. It is concluded that from an economic viewpoint,
using 2% cement is the best option.
