The study tested overall engineering properties of the mortar mixed with iron sulfate, which can replace the expensive pigment and represents colors as well. In the experiment with mortar not hardened, in cases of mixture proportion such as 1:1 or 1:3, the flow test data and air content decreased as iron sulfate increased. However, unit volume weight increased. Setting time is delayed as more iron sulfate is added. The compressive strength of the hardened mortar in 1:1 and 1:3 mixture proportion has improved with 9% or less of iron sulfate and decreased with 12% or more. As for drying shrinkage properties compared with plain and irrespective of mixture proportion, it has decreased with 6% or less of iron sulfate adding and increased with excess of 6%. Meanwhile, in regard to chromaticity, a*b* has increased as iron sulfate being added more and the case of mixture proportion of 1:1 has shown higher a*b* than that of 1:3. The value of a*b* in the mixture proportion of 1:1 was higher outdoors than indoors in the initial ageing period. At the later ageing days, a*b* of indoors remained unchanged but that of outdoors went down sharply to the level of indoors at 28 ageing days. a*b* of the mixture proportion of 1:3 showed no difference between indoors and outdoors at the initial ageing period and thereafter, a*b* of indoors remained stable while a*b* of outdoors went down and even became less than that of indoors at 28 ageing days.
