| Abstract: |
| The relationships of solid waste autoclaved samples compressive strength and their crystallinity degrees，hydrate amounts were studied with dissolved amount difference and bound water amount measured with loss on ignition and acid digestion method.The results showed that the crystallinity degrees of autoclaved samples，such as fly ash，waste glass and waste concrete are in a low level except that the crystallinity degree of autoclaved steel slag sample is higher.The dissolved amount difference，bound water amount and crystallinity degree of the autoclaved samples were related to their hydrate types.The crystallinity degrees of autoclaved samples could be indirectly represented as the ratios of well-crystallized hydrate amounts to total hydrate amounts in the autoclaved samples，and used to determine the autoclaved schedule and guide the technology optimization for autoclaved products.There is a reasonable crystallinity degree range for the compressive strength of autoclaved samples. |
