Through laboratory experiment and theoretical analysis,it is found that the structural strength of the mixture of lime and fly-ash can be promoted by the formation of space network structure,gelatin structure and gelatin-crystal structure among lime and fly-ash.

Improving of early strength of lime-flyash mixture with chemical admixtures;

The thesis theoretically analyzes the intensity structure of lime and fly ash mixture on the basis of information from survey and research, concluding that using admixture could greatly improve the early intensity of lime and fly ash granule.

The influence of the various kinds of auxiliary liming materials on the stabilities of lime milk and the lime dissolvabilities have been studied in this paper, followed by the two kinds of compound products that could be used in the liming process with satisfactory results.
