Análisis comparativo de la resistencia al corte y estabilización de suelos arenosos finos y arcillosos combinadas con ceniza de carbón

Abstract

The present experimental project prior to obtaining the Degree of Civil Engineer, aims at the stabilization of two soils of different properties with the combination of an additive as is the case of coal ash and the evaluation of the support capacity and the resistance To cut through laboratory tests. Prior to laboratory work, a visual survey was carried out to determine the location and extraction of the soils belonging to the cantons of Ambato and Puyo, once their location was identified, the samples were collected for the following tests: granulometry And Atterberg boundaries for the identification of soils according to the Unified Soil Classification System (SUCS). In order to determine the bearing capacity (CBR) of each soil, the compaction or Modified Fan test was carried out, which resulted in the maximum dry density and the optimum humidity, and then the CBR test. Combinations in three percentages of 20, 23 and 25% of coal ash. For the determination of shear strength, the unconfined compression test was performed on soils known as cangahua and high plasticity clay. The comparative analysis refers to an evaluation of properties such as humidity, plasticity, CBR strength and shear strength statistically between the two soils and their different combinations respectively, analyzing in detail the advantages and disadvantages of the use of coal ash to improve The natural properties and their use as a sub-gradient.
