Natural stone causes environmental pollution when it is collected and processed. Also, it is hard to make consistent products. Therefore, this study focuses on the artificial stone with waste porcelain to replace natural stone. The flexural strength and compressive strength are lower according to the replacement ratio of blast furnace slag in the result of experiment.

As the rapid industrialization and modernization progress of the world it is becoming a fast-paced environment pollution. And, dust or environment pollution to solve reckless diggings of natural aggregate cause a serious problem. This study was used a Blast Furnace Slag and Combined Heat and Power Plant of Fly Ash as a cement substitute to reduce $CO_2$ emissions during cement production, this study intend to suggest it's result as basic data 'Properties of Artificial Stone interior or exterior materials type utilizing industrial by-product and waste resource' utilizing Waste Porcelain and Waste Glass. As a result, it was high strength that matrix added the Combined Heat and Power Plant of Fly Ash of addition ratio 40%. Also, pre-experiment was conduct as mixing ratio of waste glass, waste porcelain on the basis of the preceding experiment, proper mixing ratio was judged that proper of waste glass, waste porcelain was mixing ratio 60, 70 (%) of appeared surface aggregate ratio more than 45%.

Recently, it is the global warming phenomenon because of the greenhouse gas exhaustion caused by and the environment problem is serious. And it is the situation where the problem of the exhaustion of resource because of the indiscriminate picking of the that is the raw material of the cement, limestone and natural aggregate are emphasized. In addition, thus the cement reduction amount of use and substitute material research is the urgent actual condition with the gas emission, which here it is generated in conducting compression molding in the building stone manufacturing process performance degradation phenomenon and fire resistance, and problem of the durability. Therefore, in this research, the waste porcelain is applied to the artificial stone and the durability property of the artificial stone according to it tries to be investigated.

The environmental problem is serious due to global warming In a concrete industry, the effort to reduce the problem of the destruction of environment arising from the indiscriminate use of limestone that is the raw material of cement and aggregate and the exhaustion of resources are continually emphasized In this research, the waste porcelain and waste glass that are the natural aggregate substitute materials were mixed and were applied. In addition, the magnesia phosphate composite and fly ash are mixed with a cement substitute material and the properties of the artificial stone was examined. Density, water absorption, rate of aggregate on the surface, compressive strength, and flexural strength were performed. As a result of the test, it is that waste glass with 60% and waste porcelain with 70% are the most excellent mix to produce the artificial stone.

Nowadays, large amount of waste pottery and porcelain annually are produced. It is needed that they are used as recycled materials in order to prevent environmental pollution and gain economic profits. Therefore, the purpose of this study is to present the method of utilizing the recycled aggregates that are obtained from waste pottery and porcelain as the concrete aggregate. The qualities of the recycled aggregate were compared with those of the crushed aggregate through measuring their physical properties. The test results showed that the replacement of crushed aggregate by recycled aggregate at the levels $10\%,\;20\%$, and $30\%$ had little effect on the compressive strength of the concretes, but higher levels of replacement reduced the compressive strength. Increment of the replacement of recycled aggregate caused increase in absorption ratio. As a conclusion, norman strength recycled aggregate concretes can be produced using less than $30\%$ of recycled aggregate.

Recently, the enviroment problem is serious due to the global warming phenomenon because of the greenhouse gas exhaustion. In addition, the effort to reduce the problem in the situation where the severity of the destruction of environment because of the indiscriminate picking of the that is the raw material of the cement, Accordingly, in the interior of a country, the industrial site using the artificial stone instead of the natural stone is increased. Thus the cement reduction amount of use and substitute material research is the urgent actual condition with the gas emission, which here it is generated in conducting compression molding in the building stone manufacturing process performance degradation phenomenon and fire resistance, and problem of the durability. limestone and aggregate and exhaustion of resource are emphasized is continued. In this research, the fly ash and waste porcelain is applied to the magnesia phosphate composite (MPC) and the characteristic of the artificial stone according to it tries to be looked into.

Porous ceramics for water-permeable paving brick was prepared by the sintering of mixed materials comprising of sewage sludge ash, waste porcelain fragment, waste glaze and low-grade clay at 1,000$^{\circ}C$ for 2 h, and the physical $.$mechanical properties, the permeability and the freeze-thaw resistance of specimens with preparation parameters were investigated. The physical mechanical properties were increased in specimens while porosity and permeability were decreased with increasing sewage sludge ash content and sintering temperature on the properties of specimens showed the opposite results. The bulk density, porosity, compressive strength and permeability (passed charge) of 30A60F specimens with 30 wt% of sewage sludge ash content, waste porcelain fragment size with 1∼2 mm and sintered at 1,000$^{\circ}C$ for 2 h were 2.17, 46.2%, 221 kgf/$\textrm{cm}^2$ and 3,150 coulombs, respectively. The permeability was increased with increasing waste porcelain fragment size, however compressive strength was decreased. The freeze-thaw resistance of 30A60F specimen with 1∼2 mm of fragment size was superior to that of the other specimens. The 30A60F specimens can be used for the water-permeable paving brick with the high permeability and adequate strength. The heavy metals included in the all specimens showed lower than the standard level.

The influx of Western culture and the food culture have altered the tableware of Korea, increasing the amount of using tableware. The representative tableware is known as bone china. Considering not only the amount of bone china waste generated from broken tableware at homes and but also faulty bone china products at factories, the bone china waste disposed in simple landfills is to be a serious environmental problem to solve. In this study, following "the research on development of ceramics body using waste celadon" of which the possibility was confirmed, development of ceramics body is conducted by recycling waste bone china. From the result of the study, it was understood that maximum addition of waste bone china was 20% of the whole material on the basis of measurement of plasticity. So 20% of pulverized bone china was added and the characteristics were evaluated, and the result was that porosity, water absorptivity and plasticity were 0.756%, 0.339% and 24.13%, respectively. Bending strength was $672\;kgf/cm^2$, which showed a good sintering condition. Therefore, it was considered that waste bone china could be utilized for development of new porcelain material.
