The aim of this experimental work was to investigate the Theological and adhesive performance of gunning mix suspensions. The results of rheological tests indicate that: the rheological curve of gunning mix bonded by high-alumina cement (HACG) is Bingham type ; the rheological curve of low cement gunning mix (LCG) bonded by mi-crosilica is characterized by pseudo-plasticity fluid with yielding stress ; and the rheological property of low-cement gunning mix bonded by microsilica is proved to be better than that of gunning mix bonded by cement. Meanwhile as indicated by the adhesive tests: the better the rheological properties of gunning mix suspension , the better the repair effect would be.
