Patologías del hormigón. Interacción entre el ataque por Sulfatos y la reacción Álcali-Árido

Abstract

The presence of both alkali-aggregate reaction and sulphate attack products In concrete samples has lead to the necessity of determining the formation sequence of such products. M.E.B.-E.D.X. studies have confirmed that silica gel is formed first and afterwards sulphates are activated, which promote the gel formation as a result of ions release to the solution
