FUNDAMENTAL STUDY ON FORMATION OF ZEOLITE FROM REACTION BETWEEN ALBITE AND PORTLANDITE

摘要

In this paper, we investigated the products of the reaction between albite and portlandite. In these experiments,albite rock reacted with calcium hydroxide in four temperature of 20, 50, 65, 80 °C, and thermogravimetricanalysis and powder x-ray diffraction were performed. XRD charts and DTG curves suggest the formationof an amorphous phase and zeolites. By comparing the relationship between Ca/ (Si + Al) ratio and the H2O/(Si + Al) ratio with previous studies, it seems that those products have a composition similar to C-S-H inhardened cement paste.
