  • Effects of the Amount of Fly Ash Modified by Stearic Acid

    Stearic is a saturated fatty acid C17 including active carboxyl group. In the standard conditions, stearic acid is a solid acid with white, light, spherical particles (density of 0,893) like the structure of fly ash ones. Stearic acid particles were dissolved in a mixture of toluene and acetone solutions.
