    Abstract

    A comparison of the ASTM slaking rate test and the German coarse grain titration test was made using results obtained from trials on hard-, medium-, and soft-burned lime. Included in the comparison were such factors as the relative slaking rate, the thermal behavior, and the effect of variations in the prescribed test procedures. Both methods proved to be reproducible and were generally suitable for industrial use. However, the German test required less time for hard-burned lime and covered a wider range of properties within its specifications. From the comparison a correlation was worked out which allowed the results of one test to be translated into those of the other test. A scaled-down version of the titration test also was developed which duplicated the results of the full-scale test.
