摘要：
A method for reducing the particle size of a pozzolanic material includes providing a pozzolanic material having an initial particle size and heating the pozzolanic material to cause a portion of the particles to at least partially fracture. Fracturing the particles creates a plurality of fissures that define sub-particles within the particles. The method also includes processing the fractured pozzolanic material to separate the sub-particles, thereby yielding the pozzolanic material having reduced particles.
