“…In the same time, important amount of waste is generated and deposit in landfill, causing serious environmental problems. The use of waste in concrete industry as a partial substitution of cement and aggregates has become an attractive alternative from environmental and economical points of view Boucedra et al, (2020) ;Shaikh, (2016); Ouldkhaou et al, (2020), Boukhelkhal et al, (2017); Djelloul et al, (2018) and (Sadek et al, 2016). The performance of concretes may be affected by the homogeneities and the characteristics (shape, texture, specific gravity, water absorption) of recycled aggregates Chen et al, (2003); Cabral et al, (2010) and Oliveira et al, (2011),e.g., recycled aggregates have been showed to reduce the workability of concrete because of their high water absorption (Leite et al, 2013).…”

The present paper investigates the hardened properties of self-compacting concrete by reusing granite waste to replace natural fin aggregates. The reuse of solid wastes as powder or aggregates allows us to produce sustainable concretes that have lower environmental impacts and reduced cost. In this work, granite waste was used as a partial replacement to natural river sand in self-compacting concrete (SCC). For this purpose, four mixtures were designed in which three contained a combination of river sand (RS) and recycled granite (RG) and one only included river sand (RS) as reference mix. Compressive strength, flexural strength, ultrasonic pulse velocity and water absorption were investigated for the hardened SCC at 28 days of hydration. The results showed that the introduction of RG has no effect on compressive strength of SCC. Adding 30% of RG increased flexural strength by 12%. According to ultrasonic pulse velocity results, the use of RG resulted in more compactness and homogeneous SCC. In addition, SCC including RG showed less water absorption.

“…The sintered glass-ceramics with high flexural strength and artistic patterns indicates better reusability of granite waste for the purpose of ornamental tiles. Boukhelkhal et al [9] investigated self-compacting concrete properties when waste marble (WMP) is employed as partial replacement of cement regarding the effect on the concrete's durability and strength characteristics. The results showed that WMP increased the water capillary absorption of the concrete and water absorption at immersion.…”

Granite Powder (GP) is industrial byproducts generated from the granite polishing and milling industry in powder form. The byproduct is left largely unused and is hazardous materials to human health because they are airborne and can be easily inhaled. GP was used as an additive to the concrete to explore the possibility of increasing the mechanical properties (compressive strength) of the concrete. The slump, compressive strength and water absorption test were performed on fresh and hardened concrete. The addition of GP to concrete to serve as an additive shows an improvement in the compressive strength of the concrete. The highest 3-day compressive strength (23.03 N/mm2) was recorded at 10% GP addition level while the lowest 3-day compressive strength (20.47 N/mm2) was recorded at 2.5% GP addition level. The highest 28-day compressive strength (28.29 N/mm2) was recorded at 10% GP addition level while the lowest 28 days compressive strength (27.40 N/mm2) was recorded at 2.5% GP addition level. Peak compressive strength of 33.40 N/mm2 was obtained at 56 days when 10% GP was added in the concrete production. The workability of the concrete decreased with increase in GP replacements. Therefore a higher water to cement ratio will be required to maintain a certain level of workability. In conclusion, employing GP as an additive in concrete helped in boosting the mechanical properties of concrete. The GP at 10% addition is the best choice among other concrete mixtures as it is equivalent to grade 30 concrete suitable for producing post tensioned concrete.
