In order to conduct the "A Study on Experiment for Improvement of Water Quality in Concrete Block Using illite and $TiO_2$ Powder", as a result of the preliminary mortar experiment, water quality purification characteristic test, pollution-resistance test, fish poison test, and the related KS-equivalent tests after manufacturing the actual concrete block, the following conclusion were deduced. As a result of the concrete block functional evaluation equivalent to KS, all the conditions showed higher compressive strength. Even though increase of absorption rate, according to illite replacement in vesicular structure, was expected as a problem, it was replaced after mixing with Titanium dioxide, and then Titanium dioxide was settled in large pores of illite so there was no problem in absorption rate.
