Particle Restructuring Unmodified clay particles Clay particles after flocculation / agglomeration
Secondary Reaction Clay participates in the secondary process Clay is converted to calcium form Calcium ions combine with dissolved silica <strong>and</strong> alumina in the clay to create additional cementitious materials Strength gain occurs
