Abstract:

Results of accelerated strength tests of cement-pozzolan and lime-pozzolan mixtures were compared with results of 28-day cement-pozzolan and 7-day lime-pozzolan tests. The accelerated cement-pozzolan strength test was one in which specimens were autoclaved at 1-day age. The accelerated lime-pozzolan strength tests in the investigation were tests of specimens at 3 days age that had been stored at temperatures of 130, 180, and 200 F. The results of the 3-day lime-pozzolan test with storage at 180 F and using reagent grade lime were comparable to the results of 28-day cement-pozzolan and 7-day lime-pozzolan tests. Part of a draft of a Federal test method for pozzolans is presented. Author
