• Resumen

  • 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.8.-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.
