Experimental study on high-moisture filling material prepared with sulphoaluminate-aluminate cement
Abstract：The properties of the high-moisture filling material prepared with sulphoaluminate-aluminate cement were studied by determing the setting time of every single slurry,setting time of the filling material,and the compressive strength of cement pastes.The results show that subsituting 5%~30% sulphoaluminate cement clinker（42.5 MPa）with the coarser aluminate cementclinker has effect on setting time of the filling material,and subtly decreases the early age（2 h） strength,and the late age strength will be largely increased,the late age（28 d） strength even exceeds that of the filling material without substitution of sulphoaluminate cement clinker to 48.9%.The high-moisture filling material prepared with subsituting 5%~30% sulphoaluminate cement clinker（42.5 MPa） with the coarser aluminate cement clinker can meet with the requirements of the standard of MT/T 420—1995.
