Consideraciones sobre el valor límite del contenido de SO4= en los áridos y materias primas para el hormigón

The present paper points out the importance of three main subjects concerning the presence of sulphur compounds in concrete: i) the maximum sulphate content of concrete aggregates specified in the Spanish concrete standard; ii) the standardized analytical method to determine sulphur compounds in agg...
