“…Initially, this phenomenon was examined with regards to possible formation of expansive gel, which may distress the material similarly to ASR, however, in plentiful calcium hydroxide conditions, no such behavior was observed (Way and Cole 1982). Nonetheless, as a consequence of alkali oxides leaching into the pore solution, the increased alkali content may lead to destabilization of other silicates in the aggregate.…”

“…Así, podemos apreciar si los áridos son o no reactivos dependiendo de los efectos que la reacción árido-álcali ha causado en cada superficie en un punto determinado (19)(20)(21)(22). Por ejemplo, en el estudio de una de las corneanas se aprecia como se disuelve el cristal de biotita después del tratamiento alcalino (Figura 6).…”

“…The results obtained upon studying the surfaces of the aggregates allowed us to determine whether an alkali-aggregate reaction had taken place (19)(20)(21)(22). For example, it was clear upon studying one of the hornfels that the biotite crystals had dissolved upon base treatment ( Figure 6).…”

“…5 g de esta fracción se trataron con 40 ml de disolución saturada de hidróxido cálcico o con disolución 1N de hidróxido sódico. Este procedimiento es similar al utilizado por Way and Cole (1982) con pequeñas diferencias; así, la temperatura de reacción se mantuvo a 25°C en lugar de los 50°C y el tiempo de reacción en 28 días en lugar de 40 días. Transcurrido ese tiempo se filtraron las disoluciones y se determinaron las concentraciones de Si, Al, Ca, P, Na y K en un espectrómetro ICP-OES Perkin Elmer 4300DV.…”
