Prediction of standard compressive strength of cement by means of accelerated testing
Abstract The present study was undertaken with a view to an accelerated testing method which would permit prediction of standard compressive strength of cement within 24 hours at most. Test specimens were 11.3×11.3 mm dry cement cylindrical compacts (average porosity 22.6% and 26.8%) cured, for 24 hours at 21°C or for 3 hours at 100°C, in distilled water or in a super-satured lime solution. A linear relation was established between the cement and the compact strength for all the four curing regimes studied. The 24 hour curing in distilled water at 21°C, however, was considered preferable, permitting strength prediction within ±11.5 kg per sq.cm at 95% confidence level. Further study on cements with a wider range of properties will be needed, however, before the method can be recommended as a substitute for current standard procedures.
