In this research, We carried out compressive, chloride ion penetration and scaling, freezing-thawing test. These test will evaluate the durability of Waste Glass Powder(WG) and Sludge(WGS) concrete. In result, the compressive strength of containing WG, WGS increased rather than OPC in age 90 days. Also, resistance of chloride ion penetration and scaling, freezing-thawing confirmed excellent rather than OPC.

Waste glass powder is efficient materials as a Supplementary Cement Materials(SCM). Recently, A number of waste glass have been occurred in glass-industry as by-products. However, almost previous research were deal with bottles, glass containers. Therefore, X-ray diffraction and thermogravimetric analysis was carried out to evaluate pozzolan reaction of various waste glass samples. Pozzolan reaction of Waste Glass Sludge(WGS) was more faster than the other waste glass samples, especially in early stage.

The quantities of waste glass have been progressively increased because of the rapid industrialization and quality of life. And, the most of them are not recycled. Concrete is the most widely used construction material, the huge amounts of natural resources are required to make concrete. So, it is needed to investigate the possibility of recycling of waste glass as concrete material ingredient. In this paper, the mechanical properties of mortar substituted the crushed heavy weight waste glass and p.s. ball as fine aggregate are compared and evaluated. From the results, it is concluded that the heavy weight waste glass can be used as fine aggregate of concrete.

Domestic expressway are exposed to damage of combined deterioration by excessive use of deicer and a lot of cost is required for maintaining damage structures. Therefore, now is the time that durability of subsidiary concrete structures is required to enhanced in order to reduce maintenance cost of structures and to promote road safety. Thus, in this study measured compression strength and scaling resistance of concrete using the waste glass sludge

Consumers increasingly prefer HDTV (high definition television), including LCD (liquid crystal display), LED (light emitting diode), and plasma TVs (television), and existing analog TV broadcasting system will be switched to digital broadcasting at the end of 2012 in Korea. Even for computer monitors, CRT (cathode-ray tube) monitors are no longer preferred because of customers’ increasing desire for thinner and lighter monitors and mobile computers. It is anticipated that these shifts will lead to a dramatic increase in disposal of analog TV sets. In 2012, it is estimated that about 117 thousand tons of CRT glass waste will be generated in Korea. CRT glass waste is not only Korea’s problem but also global issue, which needs worldwide attentions and policies for conserving useful resources and preventing groundwater pollution from heavy metals contained in CRT glass waste in case of landfill. It is important to develop BATs (best available technologies) to recycle CRT glass waste properly in short times. Therefore, in this study recycling possibility of CRT class was evaluated for the clay brick including powder of CRT glass of after crushing. Compressible strength and absorption factor of fabricated sample clay bricks were measured and observed whether they could satisfy the Korean Industrial Standard to use as normal bricks or not. The clay bricks containing under 5% of CRT panel glass powders were found to show enough quality as bricks, therefore the recycling of CRT cullet as materials of clay bricks could be utilized as one of the options.

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.

The object of this research is to confirm the effect of Waste Glass Sludge on properties of concrete through compressive strength and Alkali-Silica reaction of concrete and to develop as construction material.
