The workability of alkali activated-carbonatites-slag grouting materials with different proportioning was studied,in which Marsh cone flow time and mini-slump in combination with conventional gelation time test were adopted to characterize the apparent viscosity and yield stress of the materials.

It was studied that by using the Marsh cone flow time of subsection to substitute the rheometer to test the rheological behaviour of alkali activated carbonatites-slag grouting material pastes,and the corresponding relation of the test results of the Marsh cone flow time of subsection and the rheometer was discussed by computing of simple model.

The simulated grouting experiment of alkali activated carbonatites-slag grouting material (AACSGM) pastes was carried out in laboratory, and grouting process parameters under laboratory conditions are obtained as follows: the grouting pressure being 2.

The effect of some setting retarders on the workability of alkali-activated carbonatite-slag grouting material(AACSGM for short) was investigated.

The influence of temperature on the reaction degree,reaction product and microstructure of alkali-activated carbonatite cementitious material (C system) and alkali-activated carbonatite-slag cementitious material (CS system) was investigated by chemi- cally combined water testing,thermal analysis and scanning electron microscopy analysis.

The influence of ground granulated blast-furnace slag, strength of fly ash and metakaolin replacement, water impermeability and gel time of alkali-activated carbonatites cementitious material (AACCM for short) was studied using the orthogonal experiment.
