Study on Crystallinity Degree of Hydration Products in Autoclaved Samples with Solid Wastes

Abstract:

Article Preview

The ratio of the dissolved amount difference between in cool hydrochloride and hot hydrochloride to the bound water amount of the samples is regarded as crystallinity degree; approximate expressed the proportion relation of crystal and gel in the samples. And studied the relationship of compressive strength and dissolved amount difference, bound water amount and crystallinity degree of autoclaved silicate products using solid waste. The results shown, dissolved amount difference, bound water amount and crystallinity degree of autoclaved samples are related to kinds of hydration products. When well-crystallized hydrated amount is smaller, the crystallinity degree and its change are also smaller, and compressive strength of the sample increases with bound water amount increasing. When well-crystallized hydrated amount is larger, dissolved amount difference is larger, and crystallinity degree is larger, compressive strength of the sample increases with crystallinity degree decreased. There is an optimal value of crystallinity degree for compressive strength of the autoclaved samples.
