Degree of hydration of portland cement pastes with low water/cement ratios as influenced by curing conditions

MEASUREMENTS OF CHEMICALLY COMBINED WATER CONTENTS WERE MADE ON PORTLAND CEMENT PASTES MADE WITH WATER/CEMENT RATIOS OF 0.20 TO 0.30 BY WEIGHT. IN ADDITION TO THE FACTORS INVOLVING WATER/CEMENT RATIO, CURING MEDIUM, CURING HISTORY AND CURING PERIOD, THE DEGREE OF HYDRATION OF CEMENT PASTES CURED AT ROOM TEMPERATURE WAS SIGNIFICANTLY INFLUENCED BY THE AVAILABILITY OF ADEQUATE WATER SUPPLY DURING THE FIRST 24 HOURS OF THE CURING PROCESS. /AUTHOR/
