The aim of the study reported in this paper was to develop practical correlative models capable of predicting the compaction characteristics of clay soils blended with rubber from waste vehicle tyres. Four different clay soils, ranging from intermediate to high plasticity, were adopted for the test programme and each was blended with four different percentages of ground rubber waste. The test programme consisted of cone penetration (consistency limits) and standard Proctor compaction tests. As a result of ground rubber inclusion, the consistency limits and compaction characteristics all exhibited a linear decreasing trend with increase in rubber content. The rate of decrease, however, was greater for the high-plasticity clays. Simple correlative models, linking the compaction characteristics to the consistency limits, were suggested and validated by statistical techniques. The proposed models provide a practical procedure towards predicting the compaction characteristics of ground rubber-clay blends without the hurdles of conducting laboratory compaction tests, and thus can be implemented in practice for preliminary assessments.

Introducción: este artículo es producto de la investigación “Análisis de la resistencia y durabilidad de un suelo de cemento adicionando material no biodegradable polietileno malla Raschel (polisombra) reciclada en diferentes porcentajes en relación con el peso del suelo”, desarrollada en la Universidad de la Salle durante el 2016. Problema: identificación de las variaciones en las propiedades mecánicas de materiales de subrasante por la adición de materiales poliméricos. Objetivo: recopilar las principales investigaciones sobre las modificaciones de las propiedades de subrasante por medio de adición de fibras naturales y sintéticas, con el fin de tener una base teórica que justifique la aplicación de estas adiciones a nivel constructivo. Metodología: recopilación de bibliografía relevante sobre modificación de subrasante con polímeros y la evaluación del cambio en sus propiedades mecánicas, síntesis y discusión de resultados. Resultado: el 65 % de las investigaciones encontradas corresponde a estudios sobre las modificaciones de la resistencia a la compresión; el 30 % de ellas están dirigidas a estudios enfocados a estudiar la respuesta de los esfuerzos de tracción cuando son fibras poliméricas; y el otro 5 % evalúa propiedades como la fatiga o resistencia a la tensión axial. Conclusiones: se apunta un aumento considerable en la resistencia de compresión, que varía según el tipo o material a mezclar con el suelo y cemento. Originalidad: este artículo presenta la sustitución de materias primas de la subrasante con fibras naturales o sintéticas recicladas. Limitaciones: hasta ahora son pocas las investigaciones que se han encaminado a desarrollar modificaciones de los materiales en la subrasante con fibras naturales; por consiguiente, la información para analizar se ve limitada.

“…Common solutions to counteract the adversities associated with problematic soils, and most likely micaceous clays, include soil replacement or attempting to amend the low-graded soil by means of stabilization [ 22 ]. The former involves replacing a portion of the problematic host soil with suitable quarried/burrowed materials capable of satisfying the desired mechanical performance; this approach is often impractical due to long-haul distances, as well as other economic considerations [ 23 ]. The latter, soil stabilization, refers to any chemical, physical, biological or combined practice of altering the soil fabric to meet the intended engineering criteria [ 24 ].…”

Mechanical Performance of Jute Fiber-Reinforced Micaceous Clay Composites Treated with Ground-Granulated Blast-Furnace Slag

et al. 2019

The combined capacity of Jute Fibers (JF), the reinforcement, and Ground-Granulated Blast-Furnace Slag (GBFS), the binder, was examined as a sustainable solution towards ameliorating the inferior engineering properties of micaceous clays. A total of sixteen JF + GBFS mix designs, i.e., JF (% by total mass) = {0, 0.5, 1.0, 1.5} and GBFS (% by total mass) = {0, 3, 6, 9}, were tested for unconfined compression (UC) strength; for those mix designs containing GBFS, curing was allowed for 7 and 28 days prior to testing. Scanning electron microscopy (SEM) studies were also carried out to observe the evolution of fabric in response to JF, GBFS and JF + GBFS amendments. The greater the JF content the higher the developed strength and stiffness up to 1% JF, beyond of which the effect of JF-reinforcement led to some adverse results. The JF inclusions, however, consistently improved the ductility and toughness of the composite. The addition of GBFS to the JF-reinforced samples improved the soil–fiber connection interface, and thus led to further improvements in the composite’s strength, stiffness and toughness. The mix design “1% JF + 9% GBFS” managed to satisfy ASTM’s strength criterion and hence was deemed as the optimum choice in this investigation. Finally, a non-linear, multivariable regression model was developed and validated to quantify the peak UC strength as a function of the composite’s index properties. The proposed model contained a limited number of fitting parameters, all of which can be calibrated by little experimental effort, and thus implemented for preliminary design assessments.
