FABRE, Viviana E; BIZZOTTO, Marcela B  y  TIRNER, Jirina C. Strength Behavior of Organic Soils Stabilized with Tannin. Inf. tecnol. [online]. 2010, vol.21, n.2, pp.103-112. ISSN 0718-0764.

The aim of this work was evaluating the strength of organic soils in northeastern region of Argentina after completing the stabilization process with different types of resins. Several triaxial essays on probes of organic, natural and stabilized soils, were carried out. Treatment was materialized by adding resins to soil, in wich products obtained in the chain of production of tannin from “Quebracho Colorado”, an aldehyde and water took part. Concentration of resin was variable, as well as rate of dry weight of soil in wich it was added and the curing time. Tri - axial tests allowed drawing of intrinsic strength lines in order to  evaluate the action of stabilizer. Results indicated a rise of mechanical strength of stabilized soil, allowing identification of resin wich induced a better effect on natural soil and to extend possibilities of application of treated material.

Palabras clave : soil; stabilization; resins; tannin; strength.
