Granite Powder (GP) and Iron Powder (IP) are industrial byproducts generated from the granite polishing and milling industry in powder form respectively. These byproducts are left largely unused and are hazardous materials to human health because they are airborne and can be easily inhaled. An experimental investigation has been carried out to explore the possibility of using the granite powder and iron powder as a partial replacement of sand in concrete. Twenty cubes and ten beams of concrete with GP and twenty cubes and ten beams of concrete with IP were prepared and tested. The percentages of GP and IP added to replace sand were 5%, 10%, 15%, and 20% of the sand by weight. It was observed that substitution of 10% of sand by weight with granite powder in concrete was the most effective in increasing the compressive and flexural strength compared to other ratios. The test resulted showed that for 10% ratio of GP in concrete, the increase in the compressive strength was about 30% compared to normal concrete.Similar results were also observed for the flexure. It was also observed that substitution of up to 20% of sand by weight with iron powder in concrete resulted in an increase in compressive and flexural strength of the concrete.

“…These processes result in a mixture of water and fine particles which after drying becomes a potential problem to the environment. Granite cutting waste has been successfully used in ordinary concrete . They have concluded that granite cutting waste included concrete exhibits enhanced resistance to carbonation, chloride ion penetration, acid attack and exposure to elevated temperature at optimum granite cutting waste replacement of 25%.…”

This study aims to experimentally investigate the possibilities of reusing Granite Sawing waste (GSW) in Fibre Reinforced Self Compacting Concrete (FRSCC) using Polypropylene (PP) fibers. The effectiveness of GSW at 5, 10, 15, and 20% by weight instead of cement was investigated. The PP fibers were used at volume fractions of 0.05, 0.1, and 0.15%. In order to study the microstructure and to identify the elements of the FRSCC, SEM was used. Fresh and hardened properties were evaluated. Flyash was used as an additional mineral admixture while superplasticizer was also added to achieve required flow parameters. The GSW along with PP fibers increases the compressive strength of FRSCC. An improvement in splitting tensile strength was also observed.

“…Due to the limited mining technology in China, the granite mass will lose about 30% in the form of fine dust when it is processed into the required shape and size. In 2016, the export volume of granite stone and products in China is 7.17 million tons, and the output of granite cutting waste is about 15%, which is about 1.07 million tons per year [1].…”

Make concrete with the granite powder-based adglutinate to take place cement. Discuss the effect of substitution amount on concrete performance. With the increase of the substitution amount to cement, the compressive strength of concrete continues to decline; When it completely replaces cement and the amount of fly ash in agglutinate reaches to 20%, the 28 days compressive strength of concrete can reach 20Mpa. Moreover, the granite powder-based adglutinate with the content of 20% fly ash is used to replace cement entirely for making concrete. Research significance Foreign scholars on the granite stone powder used in concrete to make a series of [2-7], and Chinese scholars also to a series of studies, granite and other stone powder is with granite stone with single or double mixing mixing in the form of a small amount of replacing cement to make concrete, the general dosage is 5% ~ 15% [8-12]. To solve above problems, this paper put forward for the first time use is given priority to with granite stone cement does not affect the compressive strength of concrete under the condition of completely replace cement, aims to improve the utilization rate of granite stone powder and lay a foundation for later research, to solve the resource waste and environmental pollution problems provide some guidance. Experimental work Materials The granite powder-based adglutinate taken by the experiment is composed of two kinds of proportioning. The first proportioning is uniform mixed by granite powder, activator and ordinary coarse and fine aggregate; The second proportioning is uniform mixed by granite powder, fly ash, activator and ordinary coarse and fine aggregate. Granite powder is produced by a stone factory in Shanghai. The adapted cement is the conch brand ordinary portland cement of PO42.5 grade, the density is 3 200kg/m 3 , and the Blain specific surface area is 410m 2 /kg.
