OPTICAL MICROSCOPY OF CEMENT SILICATES

USED BY CERILH TO CONTROL THE MANUFACTURE OF CLINKER AND TO STUDY THE HYDRATION OF CEMENT, OPTICAL MICROSCOPY GIVES INFORMATION ON THE NATURE, SIZE, SHAPE AND DISTRIBUTION OF PHASES IN THE ROCK WHICH IT DESCRIBES. THE EXAMINATION OF MINERALS IS CARRIED OUT EITHER ON THIN LAMINA IN ORDER TO IDENTIFY THEM OR ON POLISHED SECTIONS IN ORDER THE RECOGNIZE THEM AFTER CHEMICAL ATTACK. DEPENDING ON AVERAGE HARDNESS, TIN ALUMINATE OR OXIDE IN SUSPENSION IN ALCOHOL IS CHOSEN FOR THE POLISHING OF SECTIONS. THE THIN LAMINA ARE PREPARED IN THICKNESS PROPORTIONATE TO THE DIMENSION OF THE PHASES IN THE ROCK: 30 FOR A NATURAL CRYSTALLINE ROCK, 15 FOR CLINKER, 10 FOR CEMENT PASTE. MACRO- AND MICROGRAPHY ILLUSTRATE CERTAIN ASPECTS OF THE SILICATES AND ALUMINATES ATTACKED BY VARIOUS REAGENTS. IN STUDYING THE HYDRATION OF CEMENT THE DIFFICULTY ARISING FROM THE SIZE OF GRAINS IS OVERCOME BY USING SPECIAL GRADING SYSTEMS IN WHICH THE DISTRIBUTION OF ANHYDRIDE AND HYDRATED PRODUCTS IS SHOWN. /LCPC/RRL/A/
