Significance and Use
3.1 The hydration of dead-burned dolomite grains is an important aspect of both manufacturing and using such grains. Moisture from any source will cause the grains to partially disintegrate, eventually making the dead-burned dolomite unfit for use. This test method may prove useful for determining, in a relative manner, which grains are more resistant to hydration than others.
3.2 Data from one laboratory might help in establishing internal limits for determining whether a particular batch of grain is suitable for refractory production. However, this test method takes great care to run, and is not recommended as a quality control test. Possibly, a specification might be developed between two parties if sufficient care in establishing the bias between the laboratories is carried out.
