Se estudian las reacciones sólido-solución de dos puzolanas ( toba manganeso y sílicagel) con el hidróxido de bario, utilizando un método conductimétrico. Se estudian estas reacciones en paralelo con el hidróxido de calcio, empleando métodos analíticos además del conductimétrico. Se demuestra que los cambios de los valores de la conductividad, no pueden ser relacionados con los cambios de los valores de la concentración de la solución, y que los resultados experimentales no mostraron una adecuada correlación con la ecuación de Zhuralev; específicamente la reacción con la sílicagel, no la tuvo en ningún momento.

The solid-solution reaction of two pozzolanas (toba manganese and silicagel ) with barium hydroxide by conductimetric method are studied. These reactions are studied in parallel with the calcium hydroxide, using analytic methods besides the conductrimetric. It is demonstrated that the changes of the conductivity values can't be retated with the changes in the solution concentration and that experimental results did not show an adequate correlation with the Zhuralev equation, specifically the reaction with the silicagel did not occur in any moment.
