Significance
When a powder reacts chemically with a liquid or gas at the surface of its particles, the specific surface is directly related to its rate of reaction. The measurement is therefore important in the manufacture of many processed materials. It is universally used in the cement industry as a gauge of product fineness which is directly related to such properties as speed of setting and rate of strength development.

Famous quotes containing the word significance:
“For a parent, it’s hard to recognize the significance of your work when you’re immersed in the mundane details. Few of us, as we run the bath water or spread the peanut butter on the bread, proclaim proudly, “I’m making my contribution to the future of the planet.” But with the exception of global hunger, few jobs in the world of paychecks and promotions compare in significance to the job of parent.”
—Joyce Maynard (20th century)
“The hysterical find too much significance in things. The depressed find too little.”
—Mason Cooley (b. 1927)
“History is the interpretation of the significance that the past has for us.”
—Johan Huizinga (1872–1945)
