Using grog,haydite as aggregate,high alumina cement as binder,and using compound early strength agent,the high strength haydite castable material produced successfully This castable material has the characters of early strengthened,good heat preservation,good resistance to wear,small volume density and good constraction property,etc This castable material has good utilization effect in productio

Experimental study on brittle reducing and toughening of micro-expansion high strength grouting material;
