Diseño de Adoquines de Suelo Prensado y Evaluación Complementaria de las Propiedades Físicas, Mecánicas y Químicas Funcionalizados con Aditivos tipo Organosilano Terrasil

Abstract

This research on pavers involved executing an experimental phase, classifying the material and identifying specific dosage references for constructive adobe, clay masonry, soil-cement mixes, and material testing dosages for road construction. The study follows applicable standards to evaluate physical properties such as density; chemical properties like efflorescence; and mechanical properties like the compression of pavers designed from different soil-cement mixes functionalized with an organosilane-type additive, which was used to enhance the product's strength and durability. Dosages of cement-treated soils were prepared following the PCA (Portland Cement Association), INVAS standards, and subsequently with Terrasil addition based on theoretical concepts, showing significant improvements in hardness and disproportion resistance. These properties depend on several factors, such as the soil's inherent characteristics, the cement proportion used, the mixing process, compaction, curing, and the amount of water present during stabilization. Preliminary phases, such as extraction from materials of the Tilatá Formation located in the municipality of Soracá, Boyacá, were conducted. Experimental tests were carried out in the geotechnics and structures laboratories of Universidad Santo Tomás, Tunja campus, guided by Colombian standards that establish fabrication criteria and use in the construction industry, where it serves as one of the region's primary raw materials. The results enabled establishing optimal soil-cement and Terrasil dosages for the Tilatá Formation soil, evaluating its mechanical behavior based on humidity and curing periods.
