The key to aggregate strength gain is through a cement hydration and/or pozzolanic reaction. Unlike sintered aggregate, cold-bonded aggregate is usually cured by water or covered by plastic sheets until an adequate strength is attained. Fig. 6 shows the flow diagrams illustrating the production of cold-bonded fly ash aggregate.
