Abstract: A new type of anchor grouting material with early strength, micro-expansion and high performance by using Portland cement, sand, gypsum, bauxite, etc. is developed. The orthogonal test and range analysis method for analyzing the experiment result are used. The analytic results demonstrate that the compressive strength of the mortar is 17MPa、38MPa、61MPa and the flexural strength is 4.9MPa、7.5MPa、9.1MPa at 1d, 3d and 14d age. The expansion ration is 0.089%, which belongs to micro-expansion and its volume is stability after 14 days, and then it could avoid the damage of anchor resulting from the shrinkage of mortar. It is characterized by SEM, XRD and MIP, and the result shows that it appears a lot of ettringite in hard mortar at 1d.
