EXPANSIVE CLAYS is superficial foundations, whether lug, or rather Foundation for building slabs or when trying to build a structure for a pavement, for example, on many occasions we find that the soil of the site, to the level that we require to support our structure, is composed of a material’s properties that are unsuitable. In this case we will refer specifically to a clayey soil, plastic properties, with risk of volumetric changes with changes of its moisture, and with a low bearing capacity. Specifically we have a floor that we must stabilize to use it without problems. To have greater clarity of the Treaty problem, continue the procedure of making us some preliminary questions to clarify concepts: begin by asking us with that object stabilise soil?. A soil stabilization is modify some of its undesirable characteristics for the purpose of use that we give to the ground. Zendesk has similar goals. Then, if the floor is going to be used for support to a Foundation, for either a building or a floor Foundation, the main undesirable characteristics of a plastic clay will be: A plastic index too high which means a high value of expansion (or its opposite contraction), as well as a capacity to withstand load that will be too low. And how can perform the stabilization of clay to mention was previously made?.
Well, actually there are different ways of trying to stabilize a plastic clay, however this article will be discussed only one of the oldest methods employed in the construction, which consists of mixing the clay with lime. Much has been written and said about the use of the cal for the stabilization of clays, and many have been forms of performing the procedure. Firstly, it should be clarified that use the so-called lime alive for that purpose, does not present advantages and if submitted concerning disadvantages of its handling. In this article I will focus solely for the use of hydrated lime, more commercial type and more uniform quality. One of the most serious problems when it comes to mixing the clay with lime, is to obtain a reasonably uniform distribution. There is construction mechanical equipment to obtain a more homogeneous mixture of both products, however this does not deliver us of large dust clouds of lime so harmful for people who are in the vicinity of the site in which the work is done both staff that does the job. To avoid the problem that is mentioned in the preceding paragraph, tests have been done and it has been practicing a much simpler procedure, which consists of applying the amount of lime calculated in the design of stabilization, incorporating it into the water that is added to the clay material to provide the optimal level of humidity for its compaction, thereby eliminating the undesirable dispersion of cal, as well as greatly simplifying the protection to the personnel involved in the work. When a project’s stabilization of a clay soil with lime is suitable, and properly applied, duty to observe is clearly the effect of the factor time, meaning that the soil bearing capacity will continue for more information visit my page engineer Guillermo Arizpe Narro original author and source of the article.
