Introduction to Quarry Dust
Quarry dust, a byproduct of the crushing process, is a concentrated material that can be used as aggregates for concrete, particularly fine aggregates. The rock is crushed into different sizes during quarrying activities; the dust produced during the process is referred to as quarry dust and is created as waste.
Utilization of Quarry Dust as Fine Aggregates in Concrete
Replacement for Fine Aggregates
It has been discovered that substituting 40% of the fine aggregate with quarry dust produces the strongest concrete, with the strength decreasing after that point to 50%.
Enhances Concrete Texture
Mixing quarry dust in concrete enhances the concrete texture and upto some extent strengthen the buildings.
Induces Higher Compression
Quarry dust fine particles induce higher compression in the mortar mixes, which is used to build strong structures.
- It is itself an impurity
- Low level of sustainability
- consists of fine particles
Sand and Sustainability
- Contains no impurities.
- High level of sustainability
- Consist of fine, sharp, and angular particles.
3\4 Aggregate (20mm)
In some places, 3\4 aggregate 20mm is used for chippings are implemented in place of ballast (a sand/gravel mixture) when mixing concrete. It comes in durable, recyclable bulk bags.
1 ‘’ Ballast
The coarsest type of aggregate is ballast. Although ballast is typically composed of crushed stone, it occasionally includes less desirable materials like burnt clay.
3\8 Aggregate or Chipping (10mm)
3\8 aggregate or chipping forms the common base materials for concrete slabs, asphalt, paving stones, gravel driveways, backfill materials for retaining walls, as well as applications for drainage and ornamentation.
