Silica sand is significantly used in metal foundry which is one of the essential parts of metal casting process. It is obtained from the riverbank. The demand of natural sand is significantly increasing day by day because of the increase use of casting products. To meet the ever-increasing demand for casting, silica sand is mined in large quantities.
Stone and sand products are essential for both building construction and glass manufacturing. These products are major constituents of both concrete and asphalt. Without crushed stone and sand, the construction of roads and buildings would not be possible. More than 4 tons of crushed stone and 3 tons of sand

dust as fine aggregate. (2000) M. Shukla et al. studied environmental hazardous stone dust utilization in building construction. It is found that partial replacement will not affect the strength and also solve the problem of disposal of stone dust. The workability of concrete reduces with the increase in stone dust and this
The replacement of fine aggregate with stone dust does not give any harm on strength, it gives beneficial results. But it badly affects the workability on increment level of stone dust. So for maintain workability the dose of concrete was increased which …
Quality and a steady supply of coarse and fine aggregates are the most crucial components in concrete production. Crushing basaltic stone produces coarse aggregate, …
Fine Aggregates This experiment employed locally sourced fine aggregate. Through an IS sieve, the aggregate was screened. Sand or fine aggregate could be crushed or natural. It might be found in a quarry or a riverbank. Sand particles range in size from a maximum of 4.75 mm down to 150 microns, or 0.150 mm. All of
One of the wastes that can be used in concrete is bottom ash. It is expected that bottom ash can be used as fine aggregate replacement in making concrete when natural sand is expensive to long carrying distance and has high clay content. Utilization of bottom ash as fine aggregate should be studied to alleviate the environmental
Experimental investigations reveal that quarry dust can effectively substitute for fine aggregate and cement, albeit with the caveat that a comprehensive chemical analysis of the stone dust is imperative prior to integration to ensure compatibility with the concrete mix.
The global construction industry's rapid growth has led to a meaningful rise in the consumption of gravel and sand in recent years, resulting in a scarcity of natural fine aggregate resources [1] and a shortage of natural sand. Some regions and industries utilize crushed stone fine aggregate to substitute river sand in production, and crushed stone fine aggregate finds …

Stone dust used for concrete should possess comparable fineness modulus as that of fine aggregate which is used in making concrete so that it will not absorb too much water
Stone dust is well appropriate in terms of strength and economy over normal sand for medium grade concrete (Mahzuz et al 2011). 40 percent fine aggregate can be effectively replaced …
The replacement levels of natural fine aggregate with stone dust were 30-70% at an interval of 10%. The compressive strength of specimens (100mm cubes) cast for different proportions of stone dust ...
Other is Stone dust. The Glass Powder is used as 20% replacement of the cement and Stone Dust as the partial replacement of Fine Aggregate from 0%, 10%, 20%, 30% and 40%. The grade of the concrete here is M25 and M30 grade. Slump Test …
2.1.3.1 Natural Sand: The Fine aggregates used for casting is clean river sand. Specific gravity of this sand is 2.6. Table 2: Sieve analysis of natural sand. 2.1.3.2 Bottom Ash: ... replacement of fine aggregate. The use of stone dust in concrete as partial replacement of fine aggregate will be an alternative material instead of
The aggregate tools of 2500 BCE were made of iron, bronze, and wood (quite different from the jaw crushers and screening equipment we use today). How Concrete Built The Roman Empire. Concrete is a mixture of aggregate and cement. The aggregate can be fine sand, or coarse stone, depending on its usage.
An attempt is made to study the effects of stone dust ass fine aggregate on the strength and workability aspects of concrete mixes.It is evident that the concrete strength development depends upon the strength of the cement mortar and its synergetic with coarse aggregate.
In recycled concrete, complete replacement of conventional fine aggregate by stone dust and ceramic waste is possible to achieve strength as per mix design. In recycled …
