This is a method which is adapted so as to boost up the engineering properties of soils in order to boost up its firmness. Chemical soil stabilization in most cases employs the use of chemical components in enhancing soils. Stabilization of soils is highly required whenever the soils that are available are to be used in construction projects are deemed unfit. Compaction, preconsolidation, drainage among some other processes is what is mostly entailed in these methods.
A look at some specific methods of making the soils stable, their advantages and drawbacks are explained. Also highlighted are reasons as to why some of the leading companies and the polymer-based admixture programs are more superior options for the wide majority of applications. The most commonly methods that are employed in stabilizing soils throughout the world include;
Cement stabilization - This procedure is very much common in the compaction methods. It is embraced mainly because of its nature of being cost effective in addition to the ease in availability of cement. The soil gets mixed with cement so as to boost its robustness and strength. The final results are usually durable and fair in addition to being resistant to various weathers thus making this method the ideal choice on sandy environments.
This process however is relatively intensive on labor and may also be harmful to the environment. To add onto this, while the soil cement mixture that is resulted is highly durable, it is sometime also still susceptible to getting cracks.
Lime stabilization - It is another widely popular method for stabilizing soils. The method normally is not cost effective when compared with that of using cement. It is actually made expensive due to costs incurred in burning limestone which is a requirement in the process. It poses harm to the environment. It does not however increase stability and strength especially in environments that are dry. This makes it important to increase compressive strengths in certain situations.
Chemical stabilization - These are mostly of wider groups since there are multiple applications which are unique of each other. Major benefit posed by this approach is the possibility of developing solutions which can made in such a way that they fit specific environments which are in need. Consequently, this leads to enhanced performance in addition to the reliability of this method. The chemicals adopted in this procedure are costly and are also pollutants.
Polymer stabilization - Methods which are grounded on polymers are most times up to date techniques. They do present several advantages when compared to traditional methods. Involvement in the combination of soils with materials that are polymer based is also done. Main benefit of the procedure is that they do not pollute the environment.
From the above, it is clear that various advantages are brought about by each method. Most are cost effective, durable, less prone to damage, easier to maintain and can be used in the correct proportion so as not to harm the environment. Innovative variety of products can be adopted to enhance the properties of the above methods in terms of; reducing water sensitivity, increasing water impermeability, reducing the plasticity index and increasing load bearing volume among others.
