Polymer concrete made with unsaturated polyester resin,which has good acid resistant performance,low cost and simple technological process,was studied through comparing experiments and orthogonal design experiments.This concrete was used for the electrolytic trough of smelting copper.The existing problem of seepage,bad corrosion and short life of the electrolytic trough made with ordinary concrete as the trough body and glass fiber reinforced plastic(GFRP) as the lining can be solved by this polymer concrete material.It is expected that this subject has very extensive application prospect and technological economic benefits.
