        Expanding economic growth, the increased and shortened of electronic products rapidly last a couple of decades in Korea. Furthermore, as converting to digital broadcasting system, the amount of discarded analog type TV containing cathode ray tube(CRT) glasses are increasing significantly. Accordingly, since there is no demand for CRT glass anymore, it is very important to find out how to recycle a waste CRT glass. The research was carried out to investigate the best available technologies for recycling waste CRT glass. Primary feasibility studies to find the appropriate technologies were performed in advance and then the use as aggregates of cement bricks was found as a simple and economic way of recycling CRT panel glass cullet. Based on the selection of proper technology, which is the aggregate of cement bricks fabrication using CRT glass crushed, the evaluation of recyclability were made by replacing CRT glass particles to aggregates in the mixture of cement bricks. Up to 50% of sand or stone powder was replaced and the bricks with CRT glasses were manufactured and tested in their qualities as concrete bricks. The bricks including 20 to 30% of CRT particles instead sand or stone powder were good enough to meet the standard in bending strength and absorption rate.
