The ethylene diamine, acetone and dibutyl phthalate are used as the curing agent, diluent and flexibilizer in the researches about epoxy mortar. But in fact these materials are difficult to be bought in market because of the toxicity. The influence of the additives on the workability and mechanical properties of epoxy mortar are investigated by using the orthogonal experimental design method in this work, and all the additives can be bought easily from the market. The results are as followings:(1) the influence of curing agent on the initial setting time, the toughness and the 1d, 3d compressive strength of epoxy mortar is significant; (2) the influence of diluent on the workability of epoxy mortar is significant; (3) the influence of flexibilizer on the 7d compressive strength is significant; (4) the interface bonding of epoxy mortar and cement mortar is good; (5) the optimum proportion by mass for epoxy mortar is, epoxy resin: curing agent: diluent: fumed silica =1:0.5:0.1:0.05:0.01.
