In quarrying activities, rock is extracted and transformed into aggregate of various sizes for civil engineering applications. In this process waste fine aggregates (dust waste) are generated. The disposal of this type of waste is a further cost in the extraction process, but also a possible cause of environmental pollution (e.g. leaching into water …
There is paucity of research information on effect of replacement of fine aggregate quarry dust in concrete beyond 75% and up to in concrete production. Therefore, this present study focused on investigation of strength properties of concrete produced with 0%, 25% 50%, 75% and replacement of fine aggregate with quarry dust.

This paper presents a study on the combined use of two by-products, namely quarry dust (QD) and ferronickel slag (FNS), as a full substitute for natural sand to improve the greenness of concrete production. Quarry dust was used in increments of 25% to a maximum of 75% substitution, where nickel slag was used as the remaining proportion …
Sand: Fine aggregate used in concrete and mortar, providing bulk, strength, and stability. Gravel: Coarse aggregate typically used in concrete mixes, road construction, and drainage systems. Crushed Stone: Made from crushed natural rock, it is used in construction, road bases, and as a binding material. Recycled Aggregates
Whether you need to crush 200,000 tonnes in a pit or quarry, or 2,000 tonnes of concrete recycling on a C&D job, we've got you covered with reliable, cost-effective crushing equipment from Powerscreen and …
Aggregate materials are used in a variety of construction applications, including the production of concrete, asphalt, and road base materials. They are also used for drainage and erosion control, as well …
Hence the use of Bamboo and quarry dust as replacement for coarse aggregate and fine aggregate in concrete is reducing the Environmental wastes which pose a difficult problem in its disposal. A ...
Cone crushers are compression machines that take in raw materials and reduce them in size by crushing them. A variety of industries rely on these tools, such as the concrete, aggregate, mining, coal, and natural gas industries. Inside the crusher, a piece of steel, known as the mantle, rotates eccentrically.
This work is related to study the compressive strength of concrete using quarry dust as fine aggregate instead of sand and 10mm washed aggregate instead of conventional granite.

Aggregates, both fine and coarse, constitute about 60 -80% of the concrete formula. Mixed together with cement and water, the aggregate element helps make concrete more compact, provide strength, durability and workability. These properties make concrete one of the most widely used materials across the world.
