Effect of activators on the strength of fly ash-based binder;

Complex activator for alkali slag test researching;

Effect of activator on active stimulation of wet-discharged fly-ash;

Experimental research of alkali-gel materials compound solid excitant;

The cement gelatin material with fly-ash,clinker,lime,gypsum and a few excitant is studied and produced.

The results show that we can prepare a high quality of composite Portland cement which has high strength and good other properties by blending ground steel slag, ground blast furnace slag and Portland cement, and adding some gypsum and chemical excitant correctly and properly.

In this paper,we used testing tool for testing the strength of slag-fly ash mixed cementitious system without cement clinker,and evaluated the affecting rules of the foundation material ratio and exciting agent ratio for the mixed system.

The slag grinding fineness,additives of exciting agent,modifier kind and quantity,which influence the dry contractibility and strength of slag cementing material,have been studied.

This paper introduces the experiment method and production technology for bearing brick of powdered coal ash by steam curing, with powdered coal ash as cementing material, lime and plaster as exciting agent, and coal cinder as aggregate.

The fesaibility analysis of using industrial waste phosphogypsum to produce non sintered cement stimulator;

In non sintered cement,the hydration speed and quality are determined by kind and amount of the stimulator.

The study is made on the influence of clinker admixture, complex stimulator, gypsum admixture and cement particle size distribution on highway fly ash cement.

This paper has studied the influence of fineness and activating agent on hydration and character of hard body for natural anhydrite.

This essay mainly deals with the impacts of activating agent and packing materials upon the compressive strength of compound cement which is produced according to the proper proportion of the four mixtures.

Waterproof and thermal insulation roofing material prepared from fly ash from power plant and waste plastic foam as main raw material,normal Portland cement and calcium oxide as cementitious material with a small quantity of waterproof agent,water-hating agent,activating agent is introduced.

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