“…In 2015, China's stone production was 1.117 × 10 9 m 3 , of which granite stone accounted for 6.69 × 10 8 m 3 , representing a year-on-year increase of 16.8% ,1 and the generation of granite powder more than 1.0 × 10 7 tons/year. 2 Granite powder is typically used in landfills and in the manufacture of bricks, asphalt and ceramics, resins, or composite admixtures with concrete. However, none of these methods have high utilization rates and so the environmentally friendly disposal of granite stone powder remains a challenge .3 More than 80% of the irrigated area in China relies on canal irrigation.…”

Studies were conducted using varying proportions of granite powder in canal lining concrete to determine the effect on compression resistance, impermeability and freeze–thaw cycling. The concrete microstructure was assessed using mercury intrusion porosimetry, scanning electron microscopy, and other methods. The data indicate the appearance of pore throats and demonstrate that a granite content of 10%–20% reduces the concrete strength, frost resistance, and impermeability based on changes at the microscopic level. An equation describing the relationship between the granite powder content and pore structure parameters (porosity, 20‐ to 200‐nm pore volume, and fractal dimension) was established.

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.

“…Whereas, Joel 8 found that the workability was more or less same upto 50% substation of granite dust as fine aggregate and thereafter it was improved upto 100% substitution when compared to control concrete. Li et al 9 studied the influence of granite dust mixed with manufactured sand substituted as partial replacement of fly‐ash on the properties of concrete. It was observed that due to addition of granite dust the workability was improved.…”

The brick, stone, and construction industries produces huge quantities of non‐biodegradable waste materials and incorporation of such waste materials in concrete eventually leads to the green and sustainable construction. The present paper study the effect of partial substitution of brick dust (BD), stone dust (SD), and recycled fine aggregate (RFA) as fine aggregate on the properties of natural aggregate concrete (NAC) and recycled aggregate concrete (RAC). In the present investigation, two groups of mixes were considered: Group A consists of 100% natural coarse aggregate (NCA) and group B consists of 50% NCA and 50% recycled coarse aggregate. In each group, the natural fine aggregate was partially replaced with 30% BD, 30% SD, and 30% RFA separately. All mixes were designed for M25 grade concrete with a constant w/c ratio of 0.45. The properties viz. compressive strength, density, indirect tensile strength, water absorption, ultrasonic pulse velocity of all mixes was performed. Also, durability performance of all the mixes under acid conditions viz.: HCl and H2SO4 solutions were studied. From the results it was found that the compressive strength and split tensile strengths (27.95–23.23%) of both natural and recycled aggregate concrete were significantly increased with the partial substitution of SD. Also, the results reveal that the water absorption decreased by 57.14–69.64% and 4.67–34.67%, respectively, when the replacement of NFA with BD and SD in both NAC and RAC. Both natural and recycled aggregate concrete were more susceptible for H2SO4 than HCl acid in terms of loss of weight and compressive strength.
