DIFFERENTIAL THERMAL AND THERMOGRAVIMETRIC ANALYSIS OF REACTED BENTONITE-LIME-WATER MIXTURES

摘要: THERMAL METHODS ARE APPLIED TO SUPPLEMENT PREVIOUS RESULTS BY X-RAY DIFFRACTION OF MIXTURES BENTONITE WITH CALCITIC, MONOHYDRATED, AND DIHYDRATED DOLOMITIC LIME REACTED IN THE PRESENCE WATER AT 23 C FOR 3 YEARS SEALED CONTAINERS. ADDITION, CURED WERE APPROXIMATELY 100 PERCENT RELATIVE HUMIDITY TEMPERATURES 40 80 4 5 DAYS. THESE THEN SUBJECTED HYDROTHERMAL TREATMENT SEVERAL INTERMEDIATE 170 C. INDICATED CALCIUM SILICATE HYDRATE (CSH) GEL, CSH I, POSSIBLY II ALL ROOM-CURED MIXTURES. BETTER CRYSTALLIZED PHASES, INCLUDING TOBERMORITE, RESULTED FROM TREATMENT. MOST INSTANCES, CONFIRMED USING METHODS. ADDITION THERE NEW FINDINGS; IT WAS POSSIBLE CHARACTERIZE REACTION PRODUCTS HAVING LOW DEGREES CRYSTALLINITY. A CHLORITE-LIKE MINERAL NOTED CONTAINING LIME. ALSO CLEARLY IDENTIFIED AS PRODUCT MIXTURES, PARTICULARLY THOSE TEMPERATURES. /AUTHOR/
