STUDY OF POZZOLANAS OF A VOLCANIC ORIGIN BY MEANS OF INFRARED ABSORPTION SPECTROSCOPY
ESTUDIO DE LAS PUZOLANAS DE ORIGEN VOLCANICO MEDIANTE ESPECTROSCOPIA DE ABSORCIAN INFRARRAJA
Natural Spanish pozzolanas of a volcanic origin (Canary Islands, Ciudad Real, Gerona), before and after being subjected to various treatments, have been studied by means of the technic of infrared- absorption spectroscopy for the purpose of deliving into their internal structure, which must be the basis for any future study on their pozzolanic activity. The previously referred-to treatment are: salicylic acid in a methanolic solution, calcination at 1.000 degree C and acid-base attack with later calcination at 1.000 degree C. The IR spectra obtained for each one of the pozzolanas are compared against each other. Later, the effects that each one of the treatments produce on the pozzolanas are indicated.
