Valuation of the Durability of the Concrete Used in the Precast Great Soviet Panel System
The durability of the concrete of the precast Great Soviet Panel system is valued through the resistance to compression, ultrasonic pulse velocity, surface methods, humidity and potential of corrosion.

| description | The durability of the concrete of the precast Great Soviet Panel system is valued through the resistance to compression, ultrasonic pulse velocity, surface methods, humidity and potential of corrosion. The evaluation is approached, essentially, through experimental and statistical methods, nevertheless, historical-logical and technical methods, such as surveys and interviews, are used in order to gather a bigger amount of information on the resistance to compression of the elements in the original project. While analyzing the results, we can conclude that, in elements in a good technical-constructive state that conform the constructions in exploitation, concrete has an average resistance. However, in elements with the presence of pathological damages, the resistance is low due to the fact that elements show chemical deterioration processes caused by water exposure, which generates the formation of soluble paste compounds, loss of mass, and decrease in mechanical resistance, among other alterations. At the same time, carbonation of concrete is triggered, which, in turn, causes the corrosion of the reinforcing steel. This corrosion leads to the cracking of concrete, delamination of steel, decrease of the concrete-steel adhesion, and other manifestations that affect the durability of concrete. Therefore, the incidence of the durability of concrete should be valued in the structural seismic behavior of constructions. |

Se valora la durabilidad del hormigón del sistema prefabricado Gran Panel Soviético, a través de la precisión de la resistencia a compresión, la velocidad del pulso ultrasónico y el índice esclerométrico. Igualmente, se determinan otros parámetros como la humedad y el potencial de corrosión, que también inciden en la durabilidad del hormigón. Se recurre esencialmente a métodos experimentales y estadísticos, no obstante, se emplean métodos como el histórico-lógico y técnicas como las encuestas y entrevistas, para recopilar mayor cantidad de información sobre la resistencia a compresión de los elementos prefabricados en el proyecto original. Al analizar los resultados se concluye que, en los elementos en buen estado técnico-constructivo, que conforman las edificaciones en explotación, el hormigón es de resistencia media al igual que lo prescribe el proyecto original de este sistema prefabricado. Sin embargo, en los elementos con presencia de daños patológicos la resistencia es baja. Debido a que en estos elementos se evidencian procesos de deterioro químico, causado por el ataque del agua, que generan formación de compuestos solubles de la pasta, la pérdida de masa y la disminución de resistencia mecánica entre otras alteraciones. A la par se desencadena la carbonatación del hormigón, que provoca a su vez la corrosión del acero de refuerzo. Esta corrosión conduce al agrietamiento del hormigón, delaminación del acero, disminución de la adherencia hormigón-acero y demás manifestaciones, que afectan la durabilidad del hormigón. Por lo tanto, se debe valorar la incidencia de la durabilidad del hormigón, en el comportamiento sismorresistente de estas edificaciones.
