“…Recent studies have shown the potential of granite residue for application in the construction industry, such as vi-able composite blocks based on Portland cement; granite and marble residue for residential construction (Souza, et al, 2017); quarry granitic sludge residue as SCM for cement mortar, promoting a denser matrix with a 70% improvement in resistance to chlorides (Ramos, et al, 2013); and material suitable for replacing natural raw material in tile production (Torres, et al, 2009).…”

This study explores the potential of the granite residue to be applied as a supplementary cementitious material. Furthermore, the efficiency of grinding methods in the improvement of the residue reactivity was also evaluated. The granite residue was collected in a facility located in Brazil and used as a Portland cement replacement with a substitution rate of 25% in mass. The residue was submitted to wet, dry and additive dry grinding methods, with several different times. The cement-based composites were characterized by quantitative X-Ray diffraction using the Rietveld's method, thermogravimetric analysis, and compressive strength. In conclusion, there was observed a higher efficiency of the wet grinding method, followed by an increase in compressive strength results as grinding time increased. Furthermore, the portlandite content was lower in the cement-based composite with granite residue, especially in the samples ground for 60, 120, and 180 minutes; a fact that summed up with other results for the pozzolanic potential of the granite residue.

“…This can be attributed to the fact that granite waste alone is a nonpozzolanic filler material. Ramos et al 48 reported that the 28-day compressive strength exhibited decrease for each substitution rate and that the least amount The effect of cement replacement with red granite dust (RGD) on the mechanical properties of recycled aggregate concrete (RAC) was investigated.…”

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.

“…Moreover, its physical and chemical properties are suitable for making concrete products. Also, due to its finesse, MGW is a promising material which acts as a microfiller in cement aggregate matrix (Ramos et al 2013;Bacarji et al 2013). Bahar (2010) studied the effect of using marble dust waste as a fine material on the mechanical properties of the concrete mix.…”

Background: The marble and granite industries in Egypt produce a vast amount of by-product slurry waste that could be used in green mortar production suitable for construction purposes. This research highlights the effect of the chemical constituents of marble and granite waste powders on the compressive strength of the green concrete produced. A chemical analysis of the constituents of granite and marble wastes was compared with those of the cement to study the effect of these components on the hydration reaction inside the mixture. The experiment was based on replacing the same proportions of sand and cement in the green concrete mixes with each of granite and marble waste powders after dissolving it in the water content. Results: The study revealed that by replacing 5% of cement in (NC5) mix, 10% of sand in (NF10) mix, as well as 5% of cement and 10% of sand in (NC5 + NF10) mix, by granite waste powder, the compressive strength values increased by 33%, 39%, and 41%, respectively. This was due to the presence of more than 26% fine free silica particles in granite which undergo pozzolanic reaction with calcium hydroxide present in mortar pores producing calcium silicate hydrate (CSH) crystals resulting in high strength to the cement mortar. For the same mixes containing marble powder, the compressive strength showed less values by − 14%, 10%, and 0% for NC5, NF10, and NC5 + NF10 mixes, respectively, when compared to the control mix values. Conclusion: Although the waste particles worked as filler, it was observed that its presence in the mixture improved the particle packing and increased the cohesion of the composites.
