Soil stabilization is the
process in which the enduring physical and chemical properties are altered to
get the best results while construction. This process plays a vital role in
enhancing the corporeal properties of the soil. Stabilization further elevates
the shear strength of the soil and controls the shrink-swell characteristics of
the soil.
Stabilization is carried on so
as to treat diversity of sub-grade resources varying from expansive clays to
granular materials. Stabilization is achieved with a diverse range of chemical
additives comprising lime, fly-ash, and Portland cement. The appropriate design
and testing is a noteworthy constituent for any stabilization project.
In this process, air
entraining cements and normal cements are used. Regardless of the texture of
the soil, the every kind of soil gets amalgamated with Portland cement in a
refined manner.
There are diversified
processes by which soil can be stabilized:
·
Stabilization with
lime
·
Stabilization with
cement
·
CMS
·
Stabilization with
bitumen
Lime stabilisation
can be used to increase the workability and load-bearing characteristics of the
soil. Quick lime is one of the major sources through which the quality of the
wet soil is improved. Lime substantially improves soil resilient modulus value.
Pulverization and mixing is used to combine the lime and the soil.
Cement stabilization further
increases the concreteness and sturdiness of the place where the process is
carried on. Cement stabilization is done so that the surfaced area does not
encounter any complexity in long run prospects.
CMS not just provides a
permanent modification of the soil, but it further improves the strength,
plasticity sturdiness and shrinkage limit properties. There is no requirement
of bringing special tools and equipments for stabilizing the soil with CMS,
rather the equipments that are required while lime stabilization is adequate to
get good results.
Stabilization with bitumen is
required for highway pavements so as to increase the efficiency in the soil
stabilization procedure.
Overall, these were some of
the major processes by which soil stabilization can be done.
I've always wondered how construction was able to go on even though the soil was problematic. It would be interesting to have a more detailed explanation of how soil stabilization works. I'm also a bit curious is there are more types besides concrete and lime. http://www.hiways.com.au/stabilization/technologies/subgrade-stabilisation
