EARLY ESTIMATION OF THE POTENTIAL 28-DAY STRENGTH OF PORTLAND-CEMENT BY ACCELERATED HYDRATION
TIDIG ESTIMERING AV POTENTIELL 28 DYGNS HAALLFASTHET HAS PORTLANDCEMENT GENOM ACCELERERAD HYDRATION
The aim of the study described was to work out a reliable, rapid method for early determination of the potential final strength of the portland cement produced by lohja ab, Finland. The investigation proved that the most important factor for obtaining satisfactory accuracy in such tests is how soon the test specimen is subjected to heat curing. According to the author 6 hours should be the minimum time before the hydration rate is accelerated. Within 24 hours the 28-day strength for ordinary portland cement can then be estimated with the accuracy of 1.0 mn/sq M, equal to 2.3% of the final strength. /TRRL/
