✦ Synopsis

In sulfuric acid for 56 days, the corrosion rate of the mortar treated with pulp waste liquid are 52% in I% sulfuric acid solution, 55% in 2% solution, 26% in 5% solution, 29% in I0% solution, compared to that of the mortars not treated with liquid. It is assumed that the increase of sulfuric acid resistance is due to the protective coating action by a component of waste pulp liquid and also characteristic gypsum which was formed by reaction between the mortar and sulfuric acid.
