X-RAY DIFFRACTION STUDY OF UNRETARDED AND RETARDED CEMENT PASTES

RESULTS ARE PRESENTED OF A STUDY OF THE HYDRATION OF CEMENT PASTE ALONE AND OF CEMENT PASTE CONTAINING SUGAR-LIME RETARDER. X-RAY DIFFRACTION WAS USED TO MONITOR THE PROGRESS OF HYDRATION AT VARIOUS STAGES AFTER THE INITIAL PREPARATION OF THE PASTES. IT WAS SHOWN THAT CALCIUM HYDROXIDE COULD BE DETECTED IN THE CEMENT PASTES AFTER HYDRATION WAS WELL ADVANCED AND FINAL SET WAS IMMINENT. CALCIUM HYDROXIDE COULD NOT BE DETECTED IN PASTES CONTAINING THE RETARDER. /BPR/
