Title:

LIME-CLAY MINERAL REACTION PRODUCTS

Accession Number:

Record Type:

Component

Abstract:

SEPARATE SLURRIES OF HIGH CALCIUM HYDRATED LIME OR DOLOMITIC MONOHYDRATE OR DIHYDRATE LIME WERE MADE WITH PURE BENTONITE, KAOLINITE, PULVERIZED MUSCOVITE, QUARTZ, OR VERMICULITE MINERAL AND VARIOUS AMOUNTS OF WATER. THE MIXES WERE SEALED IN PLASTIC CONTAINERS TO PREVENT LOSS OF WATER OR ENTRY OF CARBON DIOXIDE, AND CURED AT 70 F FOR TWO YEARS, AFTER WHICH X-RAY DIFFRACTION AND DIFFERENTIAL THERMAL ANALYSIS SHOWED VARYING PROPORTIONS OF CONVERSION OF MINERALS AND LIME INTO POZZOLANIC REACTION PRODUCTS. REACTION PRODUCTS WERE IDENTIFIED ON THE BASIS OF DIFFRACTOMETER D-SPACINGS. SINGLE CRYSTALS OF SEVERAL OF THE PRODUCTS WERE ISOLATED AND UNIT CELL PARAMETERS OBTAINED BY USE OF A DIFFRACTOMETER SINGLE CRYSTAL ORIENTER. DEBYE- SCHERRER POWDER DIFFRACTION DATA FROM CRUSHED SINGLE CRYSTALS ARE PRESENTED IN ASTM FORMAT AND RELATED TO THE DIFFRACTOMETER DATA. AMONG THE REACTION PRODUCTS ARE THE CALCIUM SILICATE HYDRATE 10-ANGSTRON TOBERMORITE, 8.2- AND TETRA-CALCIUM ALUMINATE HYDRATES, AND SEVERAL COMPOUNDS OF UNKNOWN COMPOSITION. /AUTHOR/
