“…Extending the curing time improves the flexural strength and crack resistance of granite waste geopolymer. The content of granite waste and water glass has the greatest impact on the flexural strength; the alkali content has little effect on the flexural strength of the geopolymer mortar [42]. When metakaolin and blast furnace slag were used as the starting materials for geopolymer synthesis, the bonding strength between the geopolymer and the granite aggregate decreased with increase in the activator modulus and the liquid/solid ratio, but it was much higher than between cement paste and granite.…”

Quarrying and processing of granite produce large amounts of waste residues. Besides being a loss of resources, improper disposal of these wastes results in pollution of the soil, water and air around the dumpsites. The main components of granite waste are quartz, feldspars and a small amount of biotite. Due to its hard and dense texture, high strength, corrosion resistance and wear resistance, granite waste may be recycled into building materials, composite materials and fine ceramics, effectively improving their mechanical properties and durability. By using the flotation process, high value-added products such as potash feldspar and albite may be retrieved from granite waste. Also, granite waste has the potential for application in soil remediation and sewage treatment. This review presents recent advances in granite waste reutilization, and points out the problems associated with its use, and the related countermeasures, indicating the scale of high value-added reutilization of granite waste.

The influence of various factors on the hardening kinetics of composite geopolymer binders based on the milled waste of magmatic rock production and processing has been investigated. The type and dosage of the binder mineral additives - granulated blast-furnace slag and fly ash - as well as the composition of the hardening activator, component dispersion, and hardening temperature have been studied as the factors determining the rate of strength development. Some analytical dependencies describing the influence of the examined factors on the strength of geopolymer magmatic rock-based binders have been developed. The dependencies developed were used to establish the requirements for process conditions of the geopolymer construction products and structures production.
