Análisis comparativo del uso de escoria de siderurgia para la estabilización de suelo

Abstract

The present experimental project aims to stabilize different types of soil of different properties by adding steel slag. Sample # 1 sandy silt soil was subtracted from the Pilisurco province of Tungurahua, sample # 2 clay soil was subtracted from the parish Murialdo province of Pastaza, sample # 3 steel slag was stolen from Canton Ambato. Once the sample and the place were identified, samples were taken from each type of soil. The necessary tests were carried out to establish the type, property and characteristics of each soil. A granulometric analysis and test for the determination of the Atterberg limits were performed to identify the type of soil according to the tables established by the Unified Soil Classification System (SUCS). The Type D Modified Proctor test was run to determine the CBR soil support capacity (California Support Ratio) which gives results of each sample tested as the maximum dry density and the optimum humidity for them to proceed with the CBR test. These tests were carried out with the soil combination plus three percentages 8, 10 and 35% of steel slag. These samples were submerged in water for three days to analyze the sponge generated by each type of soil with the combination with steel slag. For this comparative analysis, the properties and characteristics of the samples were evaluated, such as their moisture content, plasticity and support capacity, which were statistically analyzed with different combinations, resulting in an ideal alternative in which the steel slag It can be used to improve soil properties and its use as a subgrade.
