Recently, an ore of stone obtained from quarry lose its about 60% such as the muck and the stone-dust during the process of making the architectural block, the crushed aggregate and so on. A part of the muck is only reutilized for the crushed aggregate as road pavement materials, while the most of the muck in the shape of powder is mixed with water and then it is deposited in a sludge tank. The much in the shape of powder is called the stone-dust. If the stone-dust is discharged and sprayed, an ecosystem will have terrible damage because the seepage of surface water, the flow of ground water and the movement of air are not occurred smoothly by packing the void of soils. Therefore, the establishment of an efficient recycling plan are necessary through the improvement of engineering properties of the stone-dust. This study is to investigate the possibility of recycle and improvement for the Granite powder is sampled from quarry in Korea. The various strength tests are performed by use of the mixed soils with the Granite powder content ratio. As the result of various strength tests, the recycle possibility of the Granite powder is analyzed as subbase layer materials of the construction.

The development of sustainable composites materials, from recycled polymeric materials and waste from the wood industry and stone processing, allows reducing the volume of these by-products, minimizing impacts on health and the environment. Nowadays, Polypropylene (PP) is the most recycled polymer in industry, while the furniture industry has increasingly used timber felled from sustainable forest plantations as a eucalypt. The powder tailing from the ornamental stone extraction and processing industry is commonly disposed of in the environment without previous treatment. Thus, the technological option for the development of composite materials presents itself as a sustainable alternative for processing and manufacturing industries, enabling the development of new materials with special technical features. The results showed that powder granite particles may be incorporated into the polypropylene matrix associated with short eucalyptus fibres forming green hybrid composites with potential application in structural engineering, such as transport and civil construction industries.

The construction industry is under increasing pressure to adopt sustainable construction materials that reduce environmental footprints while maintaining structural performance. This review explores the potential of Ground Granulated Blast Furnace Slag (GGBS) and Granite Powder (GP) as partial replacements for cement or natural aggregates in concrete. GGBS, a byproduct of the steel industry, is known for its pozzolanic properties, which contribute to enhanced long-term strength and durability. GP is generated as a waste material from stone processing industries and offers potential as a fine aggregate replacement due to its filler effect and compatibility with cementitious systems. This paper compiles and critically analyzes the findings from the existing literature, focusing on mechanical properties such as compressive, split-tensile, and flexural strengths, along with workability, durability performance, and microstructural characteristics. Previous studies have indicated that the optimal replacement levels of GGBS and GP can significantly reduce cement and natural aggregate consumption without compromising concrete performance. This review highlights the potential of these materials for sustainable concrete production and encourages further research on their practical implementation in green construction.
