Abstract

Powder X-ray analysis of a slurry of the dolomitic lime Ca(OH)2 + MgO plus Otay bentonite, after being sealed and stored at room temperature for one year, showed complete loss of Ca(OH)2 and partial loss of the MgO, some or all of which went to Mg(OH)2. New X-ray lines indicate formation of pozzolanic reaction products. Crystals of one of these products were isolated and studied by means of a diffractometer and single crystal orienter, and the unit cell was calculated. Individual crystals were then rushed to give Debye-Scherrer powder diffraction data. The chemical composition of the crystals is not yet known. Differential thermal and X-ray analysis of the reacted limebentonite mixture shows considerable alteration of the bentonite.
