Semi‐green cementitious materials from waste granite by considering the environmental, economic, and health impacts: A review

Abstract

In this review, the studies conducted on the use of recycled waste granite (WG) in place of different components in concrete or cementitious materials, such as aggregate and cement were reviewed. In this regard; research was conducted on the reuse of WG to make economic benefit, to prevent accumulation of WG, to contribute to the environment by helping in the formation of new materials from waste material, and the use of WG, which would generate hazardous radioactive gas to human health, in concrete production. Thus, the cementitious materials that will be obtained shall be environment-friendly, economic, and helpful in the isolation of hazardous radioactive wastes. Therefore, within the scope of this study, it was investigated whether semi-green cementitious materials obtained from recycling WG would have the mechanical characteristics to satisfy the requirements, and have equivalent or even surpassing characteristics compared to materials made from classic materials. The results were obtained at a substitution rate of 5-7.5%; when recycled WG was used in place of aggregate, the results were obtained at a substitution rate of 15-25%; and when recycled WG was used in place of coarse aggregate, it gave better performance than recycled normal concrete aggregate and worse performance than crushed quartzite coarse aggregate. Furthermore, in terms of economy, it was determined that the utilization of WG would decrease costs by a minimum of 0.54% and a maximum of 2.1%; while with respect to CO 2 emissions, the use of WG could decrease worldwide CO 2 emission by 5%. Also, it was determined that the best solution for granite, which could cause gas emissions of hazardous gases such as radon gas, would be to be used in concrete that would be exposed to open air.

Valorization of granite micronized stones wastes for eco-friendly production of fired clay bricks

“…The generation of granite fine dust and coarse aggregates in millions of tonnes annually from granite industries is drastically increasing. Thus, managing large amounts of granite wastes which are stored and yet unused is a challenging problem for producers due to environmental pollution [13]. Furthermore, the storage and transportation cost to the disposal sites is considered to be among the world's future environmental problem [14].…”

Recent Advances in the Reutilization of Granite Waste in Various Fields

“…At present, disposal of granite wastes is frequently treated in simple accumulation or landfill, and its reutilization is relatively low [6]. Figure 1 shows the extent of reutilization of granite waste in construction materials in various countries [7]. It is primarily used as aggregates, fillers or additives in construction materials.…”

Experimental Study of Utilizing Recycled Fine Aggregate for the Preparation of High Ductility Cementitious Composites

“…The raw materials, such as aggregates, which occupy about 60-75% of total concrete [6], are also consumed in large quantities [4,7]. As an efficient way to reduce damage to the environment and to save non-renewable resources, recycling and crushing the construction waste into recycled aggregate for concrete has attracted much attention [2,[8][9][10][11][12]. Recycled coarse aggregate has been studied and applied to roadway construction, concrete pavement and other civil engineering works recently [4,[13][14][15][16].…”
