Expansive clays containing mineral montmorillonite exhibit swelling and shrinkage due to variations in the moisture content, leading to significant distresses. There has been a growing interest in chemical and polymer additives treated for high swelling montmorillonite clays in recent years. However, limited attention has been paid to the effect of polyacrylamide on the soil’s swelling behavior. Moreover, nontraditional methods of the soil treatment are applied for the rapid stabilization of soil. In this article, polyacrylamide polymer is used as an additive to expansive clay to control the swelling phenomenon. Three different percentages—2.5%, 5%, and 7.5%—of polymer are blended with oven-dried soil to determine Atterberg limits, compaction features, and swelling characteristics. Additionally, electrical impedance measurement is conducted on treated soil samples with different moisture contents. The electrical resistance of soils and polymer-treated soils is measured based on the electrical resistivity correlation of soils. Tests results for soils stabilized with polyacrylamide show that swelling is significantly reduced with increasing the additive content. Moreover, the addition of polymer improves resistivity of soil. Aqueous polyacrylamide can be utilized as an effective stabilization additive to enhance properties of expansive clays.

“…Finalmente, se deben incluir los sensores resistivos, cuya respuesta en voltaje depende de la mayor o menor oposición con la que se encuentra la corriente eléctrica al pasar a través del material estudiado [11]. En el caso de las escayolas, así como, en morteros y hormigones, el agua libre de amasado se va combinando progresivamente hasta ir disminuyendo la conductividad eléctrica del material, propiedad que puede relacionarse con la evolución de las propiedades mecánicas [12].…”

The hardening of the conglomerates’ materials is characterized by the change in the state of the paste, from a fluid state -after mixing- to its solid-state. At present, the well-known Vicat Needle Method is used to determine the hardening times, following the UNE-EN 13279-2 and UNE-EN 196-3 standards, depending on whether they are gypsum, plaster or cement. In this work, two alternative low-cost methods and easily applicable are proposed, based on capacitive and resistive sensors, which can help to improve the production process of prefabricated construction. The results show how it is possible to relate the setting times conventionally measured with the variations in the response of the sensors implemented. On the other hand, the behavior of the material can be monitored in real-time without having to rely on a manual test. This work, therefore, validates two alternative methods for the testing of conglomerates’ materials.
