Waste Stone and Waste Stone Powder are recycling some cyclic aggregate only. And the greater part of Waste Stone and Waste Stone Powder are reclaining or neglecting. To solve this problem, the government is proceeding development of cementitious scagliola using waste stone and waste stone powder. However, quality standard for cementitious scagliola using waste stone and waste stone powder has not been established. So cementitious scagliola using waste stone and waste stone powder has problem of quality assurance. Therefore in this study, developed standard for Evaluating Performance of cementitious scagliola using waste stone and waste stone powder through survey of international standard.

Ultra High Performance Concrete(UHPC) is a construction material that has a low water-binder ratio (W/B), a high-performance chemical admixture(SP), mixing material and steel fiber, and performance superior to that of regular concrete in terms of liquidity and strength. In the study, UHPC was used to prepare construction external panels that can replace existing stone panels. In addition, experiments were conducted to access the effects of differences in chemical admixture input amount, the number of fillers, antifoaming agent and steel fiber. An evaluation, was conducted, such of concrete compressive strength, flexural strength, impact strength, absorption rate, and frost resistance. The results showed compressive strength up to 115.5MPa, flexural strength of 20.3MPa, and an absorption rate of 1%. In this case, impact strength and frost resistance evaluation were satisfied with outward observed.

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%.
