Compared with the construction technique of common lime-fly ash aggregate,the key of basic excitation′s improving lime-fly ash aggregate lies in the chemical property of Na2SO4.

In this paper,the oil shale ash as the main raw material was used to prepare the high intensity of oil shale ash base polymer block quality,with the help of alkali-activator.

Furthermore it used orthogonal combination experiment to analyze the influence on water-cement ratio(w/b),FH content,FZ content and alkali-activator content to concrete.

The results showed that the water glass alkali activator had best effect to reinforce the compressive strength of geopolymeric cement.

Experimental study of alkali-activated compound industrial by-products;

Study on hydration mechanism of alkali-activated meta-kaolin cementitious material;

Using alkali-activated compound slag muck as cementitious materials to make environment burthen-down concrete is a kind of good approach to use various industry slag mucks effectively.

Effect of alkali activation on fly ash activity;

The results from probing into some key properties of the geoplymer show that the activating effect using water glass as a activator is not as good as using pure NaOH; the optimum proportion of slag to flyash is 4∶6 and the optimum blending ratio of alkali-activator is 10%;curing temperature of the geoplymer in water ought to be above 30℃; and cation Ca2+ plays an important ro.
