The lime was used by the Romans, and how binder to stabilize the soil in which they were to build or construct pavements. The clay stabilization is therefore a booming research field in both soil stabilization in Geotechnical look like in the restoration of buildings of adobe walls that are very present in traditional buildings in parts of the peninsula such as Castile.

Benefits of Soil Stabilization

In scientific terms, lime improves the behavior of a plastic clay because it increases the value of the liquid limit of the clay in question: thus increasing the plastic limit and plasticity index decreases both the treated clay.

Its usefulness is shown when we find expansive clays and low bearing capacity, who have a tendency acidic, i.e. pH clay expansion and therefore its thrust to expand decreases. Accordingly, the carrying capacity of the clay increases.

The land has been used as a building material since the beginning of civilization, both in making walls with adobe blocks rammed. These systems also require building be restored today. Their main problem is usually on the stabilization of walls, which are usually quite weak in contrast to the excellent qualities of these in terms of thermal and acoustic insulation. Therefore, lime usually applied to plaster walls and adobe rammed using different techniques based on the properties of the lime to stabilize clays.

Garate (Garate, 1994) discusses the use of adobe or mud Andalus, made of clay, coarse sand, rubble and lime mortar, so it should be considered a lean concrete. This supports coatings with lime mortar, pre moistened at the top descending capillary wall providing the uniform moisture. To make the plaster trowel to give two or three coats of clay, lime fat off, mulch or horsehair and sand in proportions 1:1:1 / 2: 1 or 2. Garate believed to be used for the construction of these mud walls hydraulic limes which by their clay content, were more compatible with Adobe, but says it is an issue that should be investigated.
